How do you factor x2 plus 6x-27?

Answer 1

You need to find a pair of factors of the ( -27 ) that add up to the ( 6 ).

+9 and -3 will do it.

x2 + 6x - 27 = (x + 9) (x - 3)

Answer 2

To factorise this completely you need to be aware that 216 = 63.

(x3 + 216) = (x + 6)(x2 - 6x + 36)

Answer 3

(x + 6)(x^2 - 6x + 36)

Answer 4

6(x + 6)(x + 6)

Answer 5

(x + 18)(x + 4)

Answer 6

(6x + 1)(x + 1)

Answer 7

6(x + 9)(x - 1)
