\[(6x^2+10x)-(3xy+5y)=2x(3x+5)-y(3x+5)=(2x-y)(3x+5)\]
OpenStudy (anonymous):
(6x^2+10x)-(5y+3xy) 2x(3x+5)-y|(5+3x) so (2x-y)(5+3x)
OpenStudy (anonymous):
wait so why do you group together 6x squared + 10x and 5y + 3xy
OpenStudy (anonymous):
That's called factorization by grouping, and we did that because it would give a common factor in the end, as we saw.
OpenStudy (anonymous):
Ok I got it.
