There needs to be more here, for there to be something to solve.

Yes it stands for Greatest Common Factor

so what are the two numbers that you want to find the greatest common factor of?

But why do you need GCF to solve this? It is quite simple. Just subtract 520 and carry over the x^2. That would be 15x^2

Okay thanks, how would you solve 2x²  21x=54

scarydoor Group TitleBest ResponseYou've already chosen the best response.2
that one can be solved by factorising the polynomial.

\[ 2x^2  21x =54 \] \[2x^2  21x  54 = 0 \] Now you want to solve: \[(2x + a)(x +b) = 2x^2  21x  54 \] Note that you must have \[ a*b = 54 \]

this won't always work so easily. But I can see here that it does.
