Question

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

Answer 1

Answer:

x^2 - 2x - 80

Step-by-step explanation:

IDENTITY (a+b)(a-c) : a^2 + ab - ac - bc

(x+8)(x-10)

x^2 + 8x - 10x - 80

Therefore, x^2 - 2x - 80 is the answer.

Thanks!!Hope it helps.

Answer 2

${\blue{\boxed{\underline{\underline{\mathbb{\red{SOLUTION \: :}}}}}}}$

Using the identity, (x+a)(x+b) = x ²+(a+b)x+ab

[Here, a = 8 and b = −10]

We get,

(x+8)(x−10) = x²+(8+(−10))x+(8×(−10))

= x²+(8−10)x–80

= x²−2x−80
