1)Multiply as indicated.If possible, simplify any radical expressions that appear in the product.
(4 + sqrt of 5)(10-3sqrt of 5)

=
=
---------------------
2)Solve each radical expression.
x=(sqrt of 3x+7)-3

(x+2)*(x+1) = 0
x = -2
x = -1
-----------------
3)Find each product.Write imaginary results in the form a + bi.
(7-2i)(-3+6i)
= -21 + 12 + 48i
= -9 + 48i
