Question

Find the factors of x³-3x²-10x-24

Answer 1

x3+3x2-10x-24=0

Three solutions were found :

x = 3

x = -2

x = -4

Step 1 :

Equation at the end of step 1 :

(((x3) + 3x2) - 10x) - 24 = 0

Step 2 :

Checking for a perfect cube :

2.1 x3+3x2-10x-24 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: x3+3x2-10x-24

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

Group 1: -10x-24

Group 2: x3+3x2

Pull out from each group separately :

Group 1: (5x+12) • (-2)

Group 2: (x+3) • (x2)
