Question

(x+8)(x-10) evaluate by suitable identity​

Answer 1

$\Huge\fbox{\color{red}{answer}}$

By the given Property we can expand this.

$(x + a)(x + b) = {x}^{2} + (a + b)x + ab$

$(x + 8)(x +( - 10))$

$= {x}^{2} + (8 - 10)x + (8)( - 10)$

$= {x}^{2} - 2x - 80$

Answer 2

(x+8)(x-10)

By using identity (x+a)(x+b)=x²+(a+b)x+ab

(x+8) [x+(-10)]=x²+[8+(-10)]x+8×-10

x²+(-2)x+(-80)

x²-2x-80
