Answer:
Tutorial on factoring polynomials. ... a x + a y + b x + b y = a(x + y) + b(x + y) = (a + b ) (x + y) ... 6: Difference of two cubes. x 3 - y 3 = (x - y)(x 2 + x y + y 2) 7: Difference of fourth powers. x 4 - y 4 = (x 2 - y 2)(x 2 + y 2) = (x + y)(x - y)(x 2 + y 2) ... The term (x 2 - 16) is the difference of two squares and can be factored using formula ...
