Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(2x² + 8x)=12
Factor the
leading coefficient
2*(x² + 4x)=12 -------> divide by 2-----> (x² + 4x)=6
Complete
the square. Remember to balance the equation by adding the same constants
to each side
(x² + 4x+4)=6+4
(x+2)²=10
the constant on the right side of the equation is 10
