Question

Factor X2 + 5x + 6.(x + 1)(x + 6)(x + 1)(x + 5)(x + 2)(x + 3)prime

Answer 1

The initial expression is:

$x^2+5x+6$

We need to identify the coefficients of the expressions: 1 besides x^2, 5 beside x, and 6 as a constant.

Taking into account that the coefficient of x^2 is 1, to factorize we just need to find 2 numbers whose sum is 5 and multiplication is 6.

Those numbers are +2 and +3, So the factors of the expression are:

(x + 2)(x + 3)

Because: +2 + 3 = 5

2*3 = 6

Answer: (x + 2)(x + 3)
