Question 166161: Factor completely:
x2 – 15wy + 3xy – 5wx
Answer by ptaylor(2198)   (Show Source):
You can put this solution on YOUR website! x2 – 15wy + 3xy – 5wx=
(-15wy-5wx=-5w(x+3y), so:
x2-5w(x+3y)+3xy=
(x2+3xy=x(x+3y), so:
x(x+3y)-5w(x+3y)=
(next factor out x+3y, so we have:
(x+3y)(x-5w)-----------------ans
CK using FOIL (First, Outer, Inner, Last)
x2-5wx+3xy-15wy or
x2-15wy+3xy-5wx
