How can we solve any equation by completing method? |
| Answer» To apply completing the square method, the quadratic equation must be in the form of\xa0ax2\xa0+ bx + c = 0Step 1 :In the given quadratic equation ax2\xa0+ bx + c = 0, divide the complete equation by a (coefficient of x2).\xa0If the coefficient of x2\xa0is 1 (a = 1), the above process is not required.\xa0Step 2 :Move the number term (constant) to the right side of the equation.Step 3 :In the result of step 2, write the "x" term as a multiple of 2.\xa0Examples :6x should be written as 2(3)(x).5x should be written as 2(x)(5/2).\xa0Step 4 :The result of step 3 will be in the form of\xa0x2\xa0+ 2(x)y = kStep 4 :Now add y2\xa0to each side to complete the square on the left side of the equation. Then,\xa0x2\xa0+ 2(x)y + y2 = k + y2Step 5 :In the result of step 4, if we use the algebraic identity(a + b)2 = a2\xa0+ 2ab + b2on the left side of the equation, we get\xa0(x + y)2 = k + y2Step 6 :Solve (x + y)2 = k + y2\xa0for x by taking square root on both sides.\xa0\xa0 | |

Show that 2-√3 is an irrational number |
| Answer» Let we assume that 2-√3 is R.NTherefore, it can be written as 2-√3=p/q=> 2-√3= p/q=> p - 2q/q = √3since, p and q are integerTherefore, p/q is R.NTherefore, p - 2q/q is also a R.NTherefore, √3 is also a R.NBut we know that √3 is irrational numberHere is a contradictionSo, we finally say that 2 - √3 is irrational number | |

Prove that ✓5 is irrational number |
| Answer» You should first have to assume that √5 is rational√5=p/q that is p=√5qSquaring on both side p2=5q2 P2/5=q2:.P2is divisible by 5:.p is also divisible by 5P=5 are for some integer=rSquaring on both side p2= 25r2Then it became 25r2=5q2r2=5q/25r2=q2/5Again q2 is divisible by 5And q is also divisible by 5Then we have to write reason that 5 is coom factor and p&q are co-prime. This codradiction has arise because of our incorrect assumption so we consider that root 5 is irrational number . | |
