find the zeroes of the equation: x^2+x-6=y

7 answers

Start by factoring the equation. Do you know how to do that?
is it using the FOIL method?
correct.
so i know its foil, but i'm not sure how to foil this one out.
OK. x^2 + x - 6:

Start with (x )(x )

We have to figure out 2 numbers when MULTIPLIED by each other gives -6, and when ADDED together gives 1. can you figure out these?
uhhh. no. i can't think of anything.
how about 3 and -2?

So you have (x+3)(x-2) = 0
