Question

x 2 + (a+b)x + AB =do this sum

Answer 1

Answer:

Factorizingx

Factorizingx 2

Factorizingx 2 −(a+b)x+ab,

Factorizingx 2 −(a+b)x+ab,=x

Factorizingx 2 −(a+b)x+ab,=x 2

Factorizingx 2 −(a+b)x+ab,=x 2 −ax−bx+ab,

Factorizingx 2 −(a+b)x+ab,=x 2 −ax−bx+ab,=x(x−a)−b(x−a)

Factorizingx 2 −(a+b)x+ab,=x 2 −ax−bx+ab,=x(x−a)−b(x−a)=(x−a)(x−b)
