Question

Use suitable to find the following products (x+8)(x-10)

Answer 1

Solution:

_______________________

We know the algebraic identity:

(x + a)(x + b) = x²+(a+b)x+ab

________________________

(x + 8 )(x - 10)

= (x+8)[ x + (-10)]

= x² + (8-10)x+8×(-10)

= x²-2x-80

Therefore,.

(x+8)(x-10) =x²-2x-80
