6 types of facotring and which type for each scenario
GCF-each term must have a common factor, Diff of perfect squares-in the name, Trinomial-factors that add up to b and multiply to c, borrow and payback- multiply a by c gettring rid of it then factor like trinomial, grouping, divide each area by 2 terms then find gcf, cubic bionomial-refer to cheat sheet
