You'll observe that y does not appear as a representation of any square but x does. This will be a parabola.

You'll need to Complete The Square to convert to standard form. The missing square term to apply to the x terms is %2810%2F2%29%5E2=25, but you'll need to factor a 3 first before applying this 25.

3x%5E2%2B30x=3%28x%5E2%2B10x%29.
