Equation at the end of step 1

STEP

2

:

y3 - 3y2 + y - 3

Simplify ————————————————

y2 - 9

Checking for a perfect cube :

2.1 y3 - 3y2 + y - 3 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: y3 - 3y2 + y - 3

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

Group 1: y - 3

Group 2: y3 - 3y2

Pull out from each group separately :

Group 1: (y - 3) • (1)

Group 2: (y - 3) • (y2)

-------------------

Add up the two groups :

(y - 3) • (y2 + 1)
