Factor completely.

-5x2y + 10xy - 15xy2

−5xy(x+3y−2)

Step-by-step explanation:

Factor

−5xy out of −5x2y+10xy−15xy2.

5xy*(3y+2)

Step-by-step explanation:

(1): "y2"   was replaced by   "y^2".

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 10xy +  (3•5xy2)

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  15xy2 + 10xy  =   5xy • (3y + 2)

Final result :

 5xy • (3y + 2)

Okay you have 2 sum unknow lets call them X+Y

so X+Y=33, 4X=108

Get X by it self then plug it in 4X=108

X=-Y+33
4(-y+33)= 108
-4y+132=108 Then subtract the 132
-4y=-24 Y=6 then to find X subtract 33-6=27
Y=6 X=27 if you check it works out
