We have to find two numbers whose sum is 19 and product is 18*1= 18.Clearly those numbers are 18 and 1.

x²+19x+18

x²+18x+x+18

x(x+18)+1(x+18)

(x+18)(x+1)

Answer 2

Step-by-step explanation:

${x}^{2} + 19x + 18$

$= {x}^{2} + (18 + 1)x + 18$

$= {x}^{2} + 18x + x + 18$

$= x(x + 18) + 1(x + 18)$

$= (x + 1)(x + 18)$
