Answer 2

Answer:

Factorisation of $x^{2} +15x+36$ is $(x+12) (x+3)$

Step-by-step explanation:

Factorisation by parts method

Consider the form $ax^{2} +bx+c$

Find a pair of integers whose product is  c

and whose sum is  b

In this case, whose product is  36

and whose sum is   15 .

So the integers will be 12 and 3

$x^{2} +15x+36\\ \\ x^{2} +(12+3)x + 36\\ \\ x^{2} +12x+3x+36\\ \\ x(x+12)+3(x+12)\\ \\ (x+12)(x+3)$
