twenty times the square of a non zero number is equal to 15 times the number\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x be the unknown number.\r
\n" ); document.write( "\n" ); document.write( "Then we have:\r
\n" ); document.write( "\n" ); document.write( "20*x^2 = 15x\r
\n" ); document.write( "\n" ); document.write( "Rewrite this as:\r
\n" ); document.write( "\n" ); document.write( "20x^2 - 15x = 0\r
\n" ); document.write( "\n" ); document.write( "Factor out 5x:\r
\n" ); document.write( "\n" ); document.write( "5x(4x - 3) = 0\r
\n" ); document.write( "\n" ); document.write( "The two solutions are x = 0 and 4x - 3 = 0\r
\n" ); document.write( "\n" ); document.write( "We are told that the answer is non-zero so we need only to solve 4x-3 = 0 for x.\r
