To simplify this, use the FOIL method. First, Outer, Inner, Last.
First: Multiply the first numbers in each set of parentheses.

Outer: Multiply the two outermost numbers in the equation.

Inner: Multiply the two innermost numbers in the equation.

Last: Multiply the last numbers in each set of parentheses.

Then, we put them all together in an equation, from the highest exponent to the lowest, then highest prefix (number before the variable) to lowest.

And simplify.
