Answer 1

Answer:

Step by step solution :

STEP

1

:

Equation at the end of step 1

(((x3) - 11x2) + 31x) - 21 = 0

STEP

2

:

Checking for a perfect cube

2.1 x3-11x2+31x-21 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: x3-11x2+31x-21

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

Group 1: 31x-21

Group 2: x3-11x2

Pull out from each group separately :

Group 1: (31x-21) • (1)

Group 2: (x-11) • (x2)
