Question

Use suitable identity to find the product of (x + 8) (x-10)

Answer 1

Answer:

x2 – 2x – 80

Step-by-step explanation:

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

We know that

(x + a)(x + b) = x2 + (a + b)x + ab

In the expression (x + 8)(x – 10)

•   a = 8

•   b = -10

a + b = 8 – 10 = -2

ab = 8 × (-10) = – 80

Substitute the values in the above equation

(x + 8)(x – 10) = x2 + (8 – 10)x + 8 × (-10)

(x + 8)(x – 10) = x2 – 2x – 80
