You can put this solution on YOUR website!
Solve: $\"c%5E2+%2B+c+-+20\"$ ?\r
\n" ); document.write( "\n" ); document.write( "This is an expression and you can't solve expressions but you could solve this if it were an equation such as:
\n" ); document.write( " $\"c%5E2+%2B+c+-+20+=+0\"$ \r
\n" ); document.write( "\n" ); document.write( "Let's assume that this is what you meant to write.\r
\n" ); document.write( "\n" ); document.write( " $\"c%5E2+%2B+c+-+20+=+0\"$ Solve by factoring.
\n" ); document.write( " $\"%28c+%2B+5%29%28c+-+4%29+=+0\"$ Apply the zero product principle by setting (c+5) = 0 and (c-4) = 0.
\n" ); document.write( "If $\"%28c+%2B+5%29+=+0\"$ , then $\"c+=+-5\"$
\n" ); document.write( "If $\"%28c+-+4%29+=+0\"$ , then $\"c+=+4\"$ \r
\n" ); document.write( "\n" ); document.write( "The roots of this quadratic equation are: x = -5 or x = 4\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
