Question 721541
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 {{{(10/2)^2=25}}}, but you'll need to factor a 3 first before applying this 25.


{{{3x^2+30x=3(x^2+10x)}}}.
