1)Multiply as indicated.If possible, simplify any radical expressions that appear in the product.
\n" ); document.write( "(4 + sqrt of 5)(10-3sqrt of 5)
\n" ); document.write( "\"%284%2Bsqrt%285%29%29%2A%2810-3sqrt%285%29%29\"
\n" ); document.write( "= \"40+-+2sqrt%285%29+-3%2A5\"
\n" ); document.write( "= \"25+-+2sqrt%285%29\"
\n" ); document.write( "---------------------
\n" ); document.write( "2)Solve each radical expression.
\n" ); document.write( "x=(sqrt of 3x+7)-3
\n" ); document.write( "\"x%2B3+=+sqrt%283x%2B7%29\"
\n" ); document.write( "\"x%5E2+%2B+6x+%2B+9+=+3x%2B7\"
\n" ); document.write( "\"x%5E2+%2B+3x+%2B+2+=+0\"
\n" ); document.write( "(x+2)*(x+1) = 0
\n" ); document.write( "x = -2
\n" ); document.write( "x = -1
\n" ); document.write( "-----------------
\n" ); document.write( "3)Find each product.Write imaginary results in the form a + bi.
\n" ); document.write( "(7-2i)(-3+6i)
\n" ); document.write( "= -21 + 12 + 48i
\n" ); document.write( "= -9 + 48i
\n" ); document.write( "
