Answer:
-10√5 + 30
Explanation:
This is a product of two monomials, so we would kind of like FOIL this.
F - Multiply the first terms in each set of parentheses FARTHEST TO THE LEFT.
O - Multiply the first term in the first set of parentheses FARTHEST TO THE LEFT by the last term in the second set of parentheses FARTHEST TO THE RIGHT.
I - Multiply the last term in the first set of parentheses FARTHEST TO THE RIGHT by the first term in the second set of parentheses FARTHEST TO THE LEFT.
L - Multiply the last terms in each set of parentheses FARTHEST TO THE RIGHT.
Doing this will give 5 - 10√5 + 25. Combine like-terms to end up with -10√5 + 30 [or 30 - 10√5].
