Question

X^3 + 4x^2 - 11x - 30 = (x+2) (x-3) (x+5)=0

Answer 1

STEP 1

Equation at the end of step 1

(((x3) - 22x2) - 11x) + 30

STEP 2

Checking for a perfect cube

2.1 x3-4x2-11x+30 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: x3-4x2-11x+30

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -11x+30

Group 2: x3-4x2

Pull out from each group separately :

Group 1: (-11x+30) • (1) = (11x-30) • (-1)

Group 2: (x-4) • (x2)
