When the sum of 648 and three times a positive number is subtracted from the square of the number, the result is 162. Find the number.\r
\n" ); document.write( "\n" ); document.write( "I tried to work through this but i ended up getting where i needed to square root a negative fraction, which isn't possible. Maybe i didn't write the equation right, but this is what i came up with from the question that's asked.\r
\n" ); document.write( "\n" ); document.write( "sqrt(x)-(648+3x)=162
\n" ); document.write( "
\r\n" );
document.write( "NO!  It's square, not SQUARE ROOT!!!\r\n" );
document.write( "\r\n" );
document.write( "x² - (648 + 3x) = 162\r\n" );
document.write( "\r\n" );
document.write( "Simplify then solve this as a quadratic.  You will get \r\n" );
document.write( "two answers, one is positive and one is negative.  You \r\n" );
document.write( "will discard the negative one and the positive answer\r\n" );
document.write( "is the only solution.\r\n" );
