Question

find the following products (x+ 4 )(x + 10)

Answer 1

Hii There!!
Using identity,

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

In (x + 4) (x + 10),

 a = 4 & b = 10

Now,
(x + 4) (x + 10)

= x² + (4 + 10)x + (4 × 10)
= x² + 14x+ 40

Hope it helps

Answer 2

Hello dear friend ,
here is Ur answer ..
★____________________________

$using \: the \: identity \: \\ \\ (x + a)(x + b) = {x}^{2} + (a + b)x + ab \\ we \: have \\ \: \\ (x + 4)(x + 10) \\ = {x}^{2} + (4 + 10)x + (4)(10) \\ \\ = {x}^{2} + 14x + 40$
ANS- is x^2+14x+40

Hope it's helps you.
