Need help with a math problem!How do you factor a polynomial of the form ax² + bx + c when a is not equal to 1

I'm supposed to describe the grouping approach or the reverse FOIL method but I don't know where to begin!! This is like Greek to me.

Need help with a math problem!How do you factor a polynomial of the form ax² + bx + c when a is not equal to 1
Divide the entire polynomial by "a" and then factor it like a normal equation. Because it is "a" is a constant, factoring it out first won't change the values of the variables.
Reply:My teacher was always a big fan of the guess and check method, but I'm pretty sure you could use the quadratic equation. I can't think of it off the top of my head, but check the index of your book or run a search engine on it.
Reply:You do the tic-tac-no toe method. (no toe meaning a is not 1) In this You multiply A by c and put it over B. You find the two numbers that multiply to equal a times c and add to equal B. You put these two numbers over A alone. and then plug them in for factoring.
