Factor 2x^2+5x-12

So you find out what two numbers add up to 5 and multiply to make -12

so since -12 is negative we know that the two numbers have to be diffarent signs (- times+=-)

also we see that the X^2 term is 2x^2 so we can use the 2

so the factored out form is

(2x+3)(x-4)

because the 2x times -4=-8x

the 3 times the x=3x

add them together and get 3x+(-8x)or 5x which is our middle term

and -4 times 3 =-12 which is our last term

easier

multiply -12 by two to get -24

what goes into -24 and adds to make 5?3 and 8

so the equation is 2X^2 + 8X -3X -12

this can cancel down to 2X(X+4)-3(X+4)

gather the terms to get (2X-3)(X+4)
