Question

Solve the following quadratic equations by factorization:

(a + b)2x2 - 4abx - (a - b)2 = 0

Solution

We have been given

(a + b)2x2 - 4abx - (a - b)2 = 0

(a + b)2x2 - (a + b)2x + (a - b)2x - (a - b)2 = 0

(a + b)2x(x - 1) + (a - b)2(x - 1) = 0

((a + b)2x + (a - b)2)(x - 1) = 0

Therefore,

(a + b)2x + (a - b)2 = 0

(a + b)2x = - (a - b)2

`x=-((a-b)/(a+b))^2`

or,

x - 1 = 0

x = 1

Hence, `x=-((a-b)/(a+b))^2` or x = 1

  Is there an error in this question or solution?
