You'll download A-quad program on your calculator in Gr11 Math. It's good to have one early though, as A-quad allows you to solve it within a second.
If you do not know what that is, search it up on Youtube to program it!
^Sinxe x^2 divide by 1/5 gives 5x^2, 7/5x / 1/5 -> 7 and so on. Afterwards you would get 1/5(5x^2 +7x -6). Then multiply the 5 coefficient by the ending # -6 to get -30, afterwards find 2 #'s that multiply to -30 and add up to 7x. In this case it would be 10 and -3. So the next step is 1/5(5x^2+10x-3x-6) [Basically it is still the same as having is as the equation before! But now you can factor stuff out.] Now you can factor things out 1/5(5x(x+2) -3(x+2)), then you can factor out once again so it is 1/5(5x-3)(x+2)
