CA Algebra I: Completing the Square Example 1: Factoring difference of squares Solving Quadratic Equations by Square Roots This original Khan Academy video was translated into isiXhosa by Yamkela Mgwebi.

So, dividing the whole original quadratic by 4 and totally discarding the 4 will not work if you want to leave g(x) untouched, which is desired for solving this problem. Instead, you need to factor out the 4 from the first two terms and keep the 4 outside parentheses, as the hints show.

"Rewrite the equation by completing the square: 4x^2 - 4x + 1 = 0 "The correct answer is (x-0.5)^2 = 0. My problem is that this isn't even the same parabola as the initial equation indicates. It may have the same vertex, and zeros, but the y intercept is completely different, and in fact, the entire curve is less divergent.
