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

  • math -

    Start by factoring the equation. Do you know how to do that?

  • math -

    is it using the FOIL method?

  • math -

    correct.

  • math -

    so i know its foil, but i'm not sure how to foil this one out.

  • math -

    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?

  • math -

    uhhh. no. i can't think of anything.

  • math -

    how about 3 and -2?

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