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

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

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

$= (x + 2)(x + 8)$
