Question

Use suitable identities to find the following products (x+4)(x+10)​

Answer 1

`x^2 + 14x + 40`

Explanation:

Here we gonna use the identity -

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

So using the identity here,

`(x+4)(x+10) \\=> x^2 +(4+10)x+4*10\\=>x^2+14x+40`

Answer 2

x²+14x+40 is correct answer

Explanation:

(x+4)(x+10)

=x²+10x+4x+40

=x²+14x+40

hope it helped you:)
