  • Algebra 2 -

    part of the "game" that I play is to realize that both brackets have to start with x^2 to have x^4 at the front and x^2's in the middle, so ...
    (x^2 - ...)(x^2 - ...)

    looking at the +36 at the end, I know my 2 numbers must both have the same sign, since I see a negative in the middle, they must be negative.
    Now what two factors of 36 have a sum of 13
    Gee, my game tells me it must be 9 and 4
    (x^2 - 9)(x^2 - 4)
    at this point you have to recognize the difference of square for both of those.
    final result:

    thanks for playing.
