Factor the trinomial x2+6x-27

(x+9) (x-3)

Step-by-step explanation:

Given expression is:

x²+6x-27

Split the middle term of above expression so that the sum of two terms should be 6 and the product be - 27.

x²+9x-3x-27

Making two groups and taking common, we get

x (x+9) - 3 (x+9)

Taking (x-3) as common

(x+9) (x-3)

Hence, the x²+6x-27 has two factors (x+9) (x-3).

(x-3) (x+9)

Step-by-step explanation:

x^2+6x-27 = (x-3) (x+9)

-3*9 = - 27

-3+9=6
