You can put this solution on YOUR website!
No! because with two unknowns (x and y) you couldn't do that.
\n" ); document.write( "All you need to do is to first to recognise that the x-intercept occurs at y = 0 and the y-intercept occurs at x = 0.
\n" ); document.write( "So, you can set y = 0 and solve for the corresponding value of x for the x-intercept. Let's do that first.
\n" ); document.write( "\"x%5E2%2By-36+=+0\" Set y = 0 and solve for x.
\n" ); document.write( "\"x%5E2%2B0-36+=+0\" Add 36 to both sides.
\n" ); document.write( "\"x%5E2+=+36\" Take the square root of both sides.
\n" ); document.write( "\"x+=+6\" or \"x+=+-6\" These are the x-intercepts.
\n" ); document.write( "Now set x = 0 and solve for y.
\n" ); document.write( "\"x%5E2%2By-36+=0\" Set x = 0
\n" ); document.write( "\"0%2By-36+=+0\" Add 36 to both sides.
\n" ); document.write( "\"y+=+36\" This is the y-intercept.
\n" ); document.write( "Let's look at the graph of the equation to see this result.
\n" ); document.write( "\"graph%28400%2C600%2C-10%2C10%2C-5%2C40%2C-x%5E2%2B36%29\"
