Algebra2 again

How do you:

Complete the square as an aid in graphing.

[I put exponents in ().]
y = x(2) + 4x - 2

Please Help?


The complete square of the x^2 binomial is
x^2 + 4x + 4 = (x+2)^2
Therefore, add 6 to each side of the equation and you will have this still-valid equation with a perfect squate on the right side:
y + 6 = (x + 2)^2
The function will plot as a parabola rising above the y=6 line, tangent to it at x = -2.
