Write the expression in the standard form a + bi
\n" ); document.write( "(√2/2+√2/2i)^2
\n" ); document.write( "Please help me solve this equation
\n" ); document.write( "The answer I have is a. i/2 b. -i c. i or d. -i/2
\n" ); document.write( "-------------------
\n" ); document.write( "\"%28%28sqrt%282%29%2F2%29+%2B+sqrt%28-1%29%2A%28sqrt%282%29%2F2%29%29%5E2\" I think that's what you meant.
\n" ); document.write( "Factor out \"%28sqrt%282%29%2F2%29%5E2\", which is 1/2
\n" ); document.write( "= \"1%2F2%2A%281+%2B+sqrt%28-1%29%29%5E2\"
\n" ); document.write( "=\"1%2F2%2A%281+-1+%2B+2sqrt%28-1%29%29\"
\n" ); document.write( "=\"1%2F2%2A2sqrt%28-1%29\"
\n" ); document.write( "= i
\n" ); document.write( "
\n" );
