Y=2^x y=3x

What is x and y

Factor x2y3 + xy I can factor an "x" and a "y " out of each term: x2y 3 = xy (x 1y2) = xy (xy 2) a nd xy = xy (1). x2y3 + xy = xy () = xy (xy2) = xy (xy2 + 1)

Remember: When "nothing" is left after factoring, a "1" is left behind in the parentheses.

Factor 3x3 + 6x2 - 15x. I can factor a "3" and an "x " out of each term: 3x3 = 3x (x 2), 6x 2 = 3x (2x), and

-15x = 3x (-5). Being careful of my signs, I get: 3x3 + 6x2 - 15x = 3x () = 3x (x2) = 3x (x2 + 2x) = 3x (x2 + 2x - 5)
