## How would you simplify $$a(y-b/3a)^3$$

Cannot figure out how to distribute this, please help :D- sorry about title should be $$a(y-\frac{b}{3a})^3$$

Start by writing out the terms to be multiplied:

$$a(y-\frac{b}{3a})(y-\frac{b}{3a})(y-\frac{b}{3a})$$

and just multiply terms out After you multiply the first two sets of parens, you will get a quadratic with 3 terms, and then you multiply that by the finl 2-term part in the final parens...
