PLEASE ANSWER I WILL MARK THE BRAINIEST ANSWER :)<br><br>factorise: X^2 + 10x + 16
Damm [24]

Answer:

(x+2)(x+8)

Step-by-step explanation:

1.)find factors of the third expression(16)that will add up to give the second expression(10)

16=2×8. 10=2+8

2.)substitute those factors inplace of 10

{x}^{2}  + 10x + 16

x {}^{2}  + 2x + 8x + 16

3.)factorise using grouping method

( {x}^{2}  + 2x) + (8x + 16)

x(x + 2) + 8(x + 2)

= (x + 2)(x + 8)
