Question

a minus b ka whole square intu x square minus four abx minus a minus b ka whole square

Answer 1

Answer:

b^2x^2 - 4ab - b^2

Step-by-step explanation:

I think this will help

(a-b)^2 *  (x)^2 - 4ab (-a-b)^2

a^2 - 2*a*b + b^2 * x^2 - 4ab * - ( a-b)^2      { : (a-b)^2 = (a)^2 - 2ab + (b)^2 }

a^2 - 2ab +b^2x^2 - 4ab - ( {a}^2 - 2*a*b + {b}^2 )

a^2 - 2ab +b^2x^2 - 4ab - a^2 +2ab - b^2

{ : a^2 & -a^2 cancel out , -2ab & 2ab cancel out }

b^2x^2 - 4ab - b^2
