If alpha and beta ate zeroes of x2-5x+k such that alpha+beta=1 find k. |
| Answer» x2-5x+k\xa0Here, a=1, b=-5 and c=k\xa0Now, α+ β = -b/a= -(-5)/1= 5\xa0α*β = c/a= k/7= k\xa0Now,α -\xa0β =1\xa0Squaring both sides, we get,\xa0(α -\xa0β)2=12\xa0⇒\xa0α2 +\xa0β2 - 2αβ = 1⇒ (α2 +\xa0β2 + 2αβ)\xa0- 4αβ = 1⇒ (α\xa0+β)2 -4αβ =1⇒\xa0(5)2-4k=1⇒\xa0-4k= 7-25\xa0⇒ -4k= -24\xa0⇒\xa0k=6 So the value of k is 6.\xa0 | |

Use Euclid\'s division algorithm to find the hcf of 867 and 225 |
|
Answer» By using euclid division algorithm ,The ans is _1. 867>2252. 867= 225 × 3 +192. R is not equals to 0Tgen again apply euclid divison lemma 3. 225 = 192 × 1 + 334. 192 = 33 × 5 + 275. 33 = 27 × 1 + 6 6. Finally ,27= 6 × 4 + 3 7 .At last 6 = 3 × 2 + 0 Here fiannly in 7 step R is equals to zero then the HCF of 867 and 225 is 2 Hope it help It is 3 |

Find the quadratic polynomial if two zeroes are (2+√2) and (2-√2) |
| Answer» Let zeroes be α=(2+√2) and β=(2-√2).Hence, α+β=(2+√2+2-√2) =4And, αβ = (2+√2)(2-√2) ={(2)^2-(√2)^2} = 4-2 = 2Therefore, quadratic polynomial = (x-α)(x-β)= x^2 -(α+β)x + αβ .......(I) On putting the value of (α+β) and αβ in equation (I) we get, quadratic polynomial = x^2 - 4x + 2 | |

Prove that 7root5 is irrational |
|
Answer» ? Thanks Let 7√5 be a rational number.So,7√5 = p/q.(p and q are co-prime number and q ≠ 0)=> √5 = p/7qAs, we can see that p/7q ia rational so √5 should also be rational. But this contradict the fact that √5 is irrational.So, by this we can say that 7√5 is irrational number. |
