Question

Factor the trinomial x2+6x-27

Answer 1

(x-3)(x+9)

Explanation:

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

-3*9 = -27

-3+9=6

Answer 2

(x+9)(x-3)

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).
