Solve for x:
\n" ); document.write( " $\"y+=+-5x%5E2%2Bx%2B4\"$ Set y = 0.
\n" ); document.write( " $\"-5x%5E2%2Bx%2B4+=+0\"$ Factor the trinomial.
\n" ); document.write( " $\"%28-5x-4%29%28x-1%29+=+0\"$ Apply the zero product rule.
\n" ); document.write( " $\"-5x-4+=+0\"$ or $\"x-1+=+0\"$
\n" ); document.write( "If $\"-5x-4+=+0\"$ then $\"-5x+=+4\"$ and $\"highlight%28x+=+-4%2F5%29\"$
\n" ); document.write( "If $\"x-1+=+0\"$ then $\"highlight%28x+=+1%29\"$
\n" ); document.write( "Graph:
\n" ); document.write( " $\"graph%28400%2C400%2C-5%2C5%2C-5%2C5%2C-5x%5E2%2Bx%2B4%29\"$ \n" ); document.write( "
