:

Equation at the end of step

2

:

((14 • (x3)) + ((3•7x4) • y)) - (22•7x2y2)

5

:

Pulling out like terms

5.1 Pull out like factors :

21x4y + 14x3 - 28x2y2 = 7x2 • (3x2y + 2x - 4y2)

Trying to factor a multi variable polynomial :

5.2 Factoring 3x2y + 2x - 4y2

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result :

7x2 • (3x2y + 2x - 4y2)
