do you know how to factor?
OpenStudy (precal):
I would factor out a GCF from all three terms, then factor what is left
OpenStudy (precal):
so what is your GCF?
OpenStudy (anonymous):
To simplify it take out a GCF(Greatest Common Factor) so in this case 2 so you will get 2(x^2-4x-21)
OpenStudy (anonymous):
Because you pulled the 2 away from 2x^2, then divided 8/2=4, the divided 42/2=21
