Solve for x:
\n" ); document.write( " $\"3x%5E2+=+15\"$ Divide both sides by 3.
\n" ); document.write( " $\"x%5E2+=+5\"$ Take the square root of both sides.
\n" ); document.write( " $\"x+=+sqrt%285%29\"$ or $\"x+=+-sqrt%285%29\"$ These are the x-intercepts as you can see by the graph of the equivalent equation: $\"y+=+x%5E2-15\"$
\n" ); document.write( " $\"graph%28400%2C400%2C-5%2C5%2C-17%2C5%2C3x%5E2-15%29\"$ \n" ); document.write( "
