Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

((15 • (x2)) - 6xy) - 32y2

STEP

2

:

Equation at the end of step

2

:

((3•5x2) - 6xy) - 32y2

STEP

3

:

STEP

4

:

Pulling out like terms

4.1 Pull out like factors :

15x2 - 6xy - 9y2 = 3 • (5x2 - 2xy - 3y2)

Trying to factor a multi variable polynomial :

4.2 Factoring 5x2 - 2xy - 3y2

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

Found a factorization : (x - y)•(5x + 3y)

Final result :

3 • (x - y) • (5x + 3y)
