Question

using factoring and the zero product property to find the zeros of each quadratic function. f(x)=4x^2+4x-24

Answer 1

factor out 4

\[f(x) = 4(x^2 +x - 6)\]

now factor the quadratic....

hope it helps

Answer 2

i got that far, but like i dont really know what to do afterwards.

Answer 3

ok... so what are the factors of -6 that add to 1

the larger factor is positive... and the smaller negative

so

f(x) =4(x + factor1)(x + factor 2)

Answer 4

so then, f(x)=4(x+3)(x-2)?

Answer 5

yep... now to find the zeros

solve

x + 3 = 0

x -2 = 0

Answer 6

oooh okay thnak yooou ^_^
