**Re: Need help factoring**

check the problem . I believe it should be 14x^2-x-15

14x^2 -x +15

factors of 14

1,14..... 2,7

factors of 15

1,15...3,5

we want a set whose sum of products add to 1

none exist, use binomial equation

x=-b+/- square root [b^2-4ac] all over 2a

x=1+/-[1-4[14][15]]^1/2 all over 28

x=1+/- [ 1-840]^1/2 all over 28

x=1+/- sqrt[-839] all over 28 complex roots

if the problem was

14x^2-x-15

we would have

[14x-15][x+1] answer
