    K for part 1, all you have to know for the first problem is what factors when multiplied eqaul -36, do you know that? :)

    That doesn't equal -36 when multiplied, but -6*6 does :)

    Now all you would do is (x-6)(x+6) to factor the quadratic equation. Wait is that what you needed?

    K so we have x^2= 8x-12. We can make this x^2-8x+12=0

    Now you need to find out what factors when multiplied to 12, add up to -8. Can you think of anY? :)

    sooo....(x+4) (x-4)

    Not necessarily. 4*-4=-16. We need two numbers like -6*-2 that equal 12 and add up to -8 :) Since those two numbers are it we can factor our quadratic equation as (x-6)(x-2)
