Question

Find the factors and the zeros.
x^2+2x-24

Answer 1

Well, what multiplies to -24 and adds up to 2?

Answer 2

-4 and 6, right?

Answer 3

(x-4)(x+6) -> x^2+6x-4x-24 -> x^2+2x-24 yep!

So, then set each of these to equal 0.
x-4=0 x=4
x+6=0 x=-6

-6 and 4 are the zeros :)

Answer 4

wow your good at this how did you find it and how to i get the factors?

Answer 5

if the eqn were ax^2+bx +c =0 then multiply axc...
now you have to simplify the coeff of x in such a manner that the seperated values also multiply to give axc.
Writing factors of axc helps....

Answer 6

You just find what multiplies to -24 and adds to +2...easy peasy :)
