STEP

5

:

Pulling out like terms

5.1 Pull out like factors :

-4x2 - 4xy + 6y2 = -2 • (2x2 + 2xy - 3y2)

Trying to factor a multi variable polynomial :

5.2 Factoring 2x2 + 2xy - 3y2

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

Factorization fails

Final result :

-2 • (2x2 + 2xy - 3y2)
