Algebra.Com's Answer #349660 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! clear the complex number from the denominator by FOILing the numerator AND denominator with the conjugate, (1 - 2i)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "remember, i^2 is -1 \n" ); document.write( " |
