Standard form is 
where A is a positive number.



Add -2x2 to both sides



Rearrange terms in descending order on the left.
Right side becomes 0:



Since first term is negative, multiply every term by -1:

  <--- that's in standard form.  That's
                        all you were asked to do.  But
                        I'll go ahead and solve it.  

Factor the left side:



Use zero-factor property:
