When completing the square, what do you do to b?

The first step to solving quadratics by factoring is to....

• isolate the x² or the (x - h)².

• move everything to one side and set it equal to zero.

• get the x² + bx on one side and set it equal to the constant.

• move everything to one side and set it equal to zero so you can find a, b and c values.
