14817.	Factorise a^3b^3-64 (a+b)^3
Answer» ★ ANSWER : To factorise : a³b³ - 64(a + b)³ Solution : a³b³ = (ab)³ 64 = 4³ 64(a+ b)³ = 4³(a+b)³ = {4(a+b)}³ = (4a + 4b)³ SIMPLIFIED FORM : factorise : (ab)³ - (4a + 4b)³ We know that , a³ - b³ = (a - b) (a² + ab + b²) by using the formula (ab)³ - (4a + 4b)³ {(ab) - (4a + 4b)} {(ab)² + (ab)(4a + 4b) + (4a + 4b)² } identity - (a +b)² = a² + 2ab + b² (ab - 4a - 4b) {a²b² + 4a²b + 4ab² + 16a² + 16b² + 32ab } → (ab - 4a - 4b) (a²b² + 4a²b + 4ab² + 16a² + 16b² + 32ab)

14817.

Factorise a^3b^3-64 (a+b)^3

Answer»

★ ANSWER :

To factorise :

a³b³ - 64(a + b)³

Solution :

a³b³ = (ab)³

64 = 4³

64(a+ b)³ = 4³(a+b)³

= {4(a+b)}³ = (4a + 4b)³

SIMPLIFIED FORM :

factorise :

(ab)³ - (4a + 4b)³

We know that ,

a³ - b³ = (a - b) (a² + ab + b²)

by using the formula

(ab)³ - (4a + 4b)³

{(ab) - (4a + 4b)} {(ab)² + (ab)(4a + 4b) + (4a + 4b)² }

identity -

(a +b)² = a² + 2ab + b²

(ab - 4a - 4b) {a²b² + 4a²b + 4ab² + 16a² + 16b² + 32ab }

→ (ab - 4a - 4b) (a²b² + 4a²b + 4ab² + 16a² + 16b² + 32ab)

17. ABCD is a parallelogram. The sides AB, ADare produced to E, F so that AB = BE and AD =DF. Prove that the triangles BEC and DCF arecongruent..... please answer ASAP ....

Answer»

Given:

AB = BE = CD and BC = AD = DF

in a Parallelogram ∠BAD = ∠CDF

in Parallel Lines (CONGUGATE ANGLES) ∠EBC = ∠BAD

So, ∠BAD = ∠CDF = ∠EBC

To Prove :

ΔBEC ≅ ΔDCF

Proof :

Side -> EB = CD

Angle -> ∠CDF = ∠EBC

Side -> BC = DF

Hence, Through SAS ΔBEC ≅ ΔDCF

Answer» An infinite geometric series is the sum of an infinite geometric sequence . This series would have no last term. The GENERAL form of the infinite geometric series is a1+a1r+a1r2+a1r3+... , where a1 is the first term and R is the common ratio. We can find the sum of all finite geometric series. We can find the sum of all finite geometric series. But in the case of an infinite geometric series when the common ratio is greater than one, the terms in the sequence will get larger and larger and if you add the larger NUMBERS, you won't get a final answer. The only possible answer would be infinity. So, we don't deal with the common ratio greater than one for an infinite geometric series. If the common ratio r lies between −1 to 1 , we can have the sum of an infinite geometric series. That is, the sum exits for \| r \|<1 . The sum S of an infinite geometric series with −1 S=a11−r An infinite series that has a sum is called a convergent series and the sum Sn is called the partial sum of the series. You can use sigma notation to represent an infinite series. For example, ∑n=1∞10(12)n−1 is an infinite series. The infinity symbol that PLACED above the sigma notation indicates that the series is infinite. To find the sum of the above infinite geometric series, first check if the sum EXISTS by using the value of r . Here the value of r is 12 . Since ∣∣12∣∣<1 , the sum exits. Now use the formula for the sum of an infinite geometric series. S=a11−r Substitute 10 for a1 and 12 for r . S=101−12 Simplify. S=10(12) =20

14835.	Prove that √12 is irrational
Answer» Answer: A rational number is what we can express as a fraction of two integers. like $\frac{p}{q}$ . If we could express $\sqrt{12}$ as a fraction then it WOULD be a rational number. But we can't do it so it is irrational. Step-by-step explanation: Let's SAY . $\sqrt{12}$ is rational. so we could WRITE it as a fraction of two rational numbers $\frac{p}{q}$ . $\sqrt{12} = \frac{p}{q}\\ (\sqrt{12})^2 = (\frac{p}{q})^2\\12 = \frac{p^2}{q^2}\\12q = \frac{p^2}{q} \\$ look, p and q both are integers. so 12q would be also an INTEGER. but $\frac{p^2}{q}$ can't be an integer as p is integer and q is also integer. so it would be a fraction . so, $12q \neq \frac {p^2}{q}$ so $\sqrt{12}$ can't be a rational number. So it is obviously an irrational value.

Prove that √12 is irrational

Answer»

Answer:

A rational number is what we can express as a fraction of two integers.

like $\frac{p}{q}$ . If we could express $\sqrt{12}$ as a fraction then it WOULD be a rational number. But we can't do it so it is irrational.

Step-by-step explanation:

Let's SAY . $\sqrt{12}$ is rational.

so we could WRITE it as a fraction of two rational numbers $\frac{p}{q}$ .

$\sqrt{12} = \frac{p}{q}\\ (\sqrt{12})^2 = (\frac{p}{q})^2\\12 = \frac{p^2}{q^2}\\12q = \frac{p^2}{q} \\$

look, p and q both are integers. so 12q would be also an INTEGER. but $\frac{p^2}{q}$ can't be an integer as p is integer and q is also integer. so it would be a fraction .

so, $12q \neq \frac {p^2}{q}$

so $\sqrt{12}$ can't be a rational number.

So it is obviously an irrational value.

If alpha beta are the zeros of the polynomial X square + 2 X + 1 then find the value of alpha + beta

Answer»

Answer:

-2

Step-by-step explanation:

Hii MATE,

we have to find here the sum of zeroes of given EQUATION.

Shortcut method:

general FORM of a quadratic polynomial

x²-(sum of zeroes)X+(product of zeroes)=0

comparing it with given equation x²+2x+1=0 => x²-(-2)x+1=0, we get

Sum of zeroes= -2

General method:

given equation,

x²+2x+1=0

=>x²+x+x+1=0

=>x(x+1)+1(x+1)=0

=>(x+1)(x+1)=0

=>(x+1)=0 or (x+1)=0

=>x=α= -1 and x=β= -1

so, α+β=(-1)+(-1)=-1-1= -2
