factor 5x^2+5x-10

hartnn (hartnn):

can you factor out 5 first ? from that expression ?

OpenStudy (anonymous):

He means you can take a 5 out of each term Isn't it the same as 5(x^2 + x - 2)

OpenStudy (anonymous):

You can then use reverse FOIL to figure out the rest 5(x+2)(x-1) Does that make sense?
