Question

evaluate using suitable identity
(X+10)(x-8)​

Answer 1

Answer: x^2 + 2x - 80 is the solution

Step-by-step explanation:

To find the product of (x + 8)(x – 10)

We have to find the solution,

We know that,

(x + a)(x + b) = x^2 + (a + b)x + ab

In the expression (X+10)(x-8)​

a = 10

b = -8

a + b = 10 – 8= 2

ab = 10 × 8 =  80

Substitute the values in the above equation

(X+10)(x-8)​ = x^2 + (-8 + 10)x - 8 × 10

(x + 8)(x – 10) = x^2 + 2x - 80

x^2 + 2x - 80 is the solution
