Simplify by taking the square root of both sides. 2 2 x 2 12 2 x 7 2 0 2. For example x²6x5 isnt a perfect square but if we add 4 we get x3².
A x 2 b x c.
1 per month helps. In symbol rewrite the general form. Divide both sides by the coefficient of x -squared unless of course its 1. Put the equation into the form ax 2 bx c.
