Then, what about 120x^2-34x-21=0 (The same procedures as the one above) Thank you so much again.

**Reiny**, Monday, November 10, 2008 at 5:41pmfor x^2 - 625 =0

it factors to (x+25)(x-25)= 0

take it from there

120x^2-34x-21=0

I used the formula to find the solutions of x=7/12 and x=-3/10

so the factored form must be

(12x-7)(10x+3) = 0
