Answer: -m*(x-3y)*(3x-y)

(*=multiply btw)

Explanation:

STEP 1:

Equation at the end of step 1

(m • ((x + y)2)) - 4m • (x - y)2

STEP2:

Equation at the end of step 2

m • (x + y)2 - 4m • (x - y)2

STEP3:

3.1 Evaluate : (x+y)2 = x2+2xy+y2

3.2 Evaluate : (x-y)2 = x2-2xy+y2

STEP4:

Pulling out like terms

4.1 Pull out like factors :

-3mx2 + 10mxy - 3my2 = -m • (3x2 - 10xy + 3y2)

Trying to factor a multi variable polynomial :

4.2 Factoring 3x2 - 10xy + 3y2

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

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