Use the grouping method to factor the following polynomials. $$ a x+a y+b x+b y $$

Use the grouping method to factor the following polynomials. When factoring the polynomial \(8 a^{2} b^{4}-4 b^{4}+14 a^{2}-7\) in Sample Set A, we grouped together terms 1 and 2 and 3 and 4 . Could we have grouped together terms 1 and 3 and 2 and \(4 ?\) Try this. \(8 a^{2} b^{4}-4 b^{4}+14 a^{2}-7=\)

For the following problems, factor the binomials. $$ b^{2}-36 $$

Factor the following problems, if possible. $$ 10 x^{2}+33 x+20 $$

For the following problems, use the grouping method to factor the polynomials. Some may not be factorable. $$ a(a+6)-(a+6)+a(a-4)-(a-4) $$

For the following problems, factor the polynomials. $$ A x-A y $$
