    Answer:

    Changes made to your input should not affect the solution:

    (1): “y2” was replaced by “y^2”. 2 more similar replacement(s).

    STEP

    1

    :

    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)
