Question

Factorise:
x^2 + 6x +8

Answer 1

(x+4)(x+2)

Explanation:

To factorize:

two number that your sum = 6

two number that your multiplication = 8

The numbers are:

4 and 2

then:

x² + 6x + 8 = (x+4)(x+2)

Answer 2

(x + 4)(x + 2)

Explanation:

x^2 + 6x + 8

If this can be factorised, then we end up with

x^2 + 6x + 8 = (x + ___)(x + ___)

To fill in the blanks, we need two numbers whose product is 8 and whose sum is 6.

The numbers are 4 and 2.

x^2 + 6x + 8 = (x + 4)(x + 2)
