How to solve by completing a square
WebTo factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) … WebThe formula for solving a quadratic equation using the completing the square method relies on the square root principle. Given any quadratic equation of the form ax2 + bx + c = 0 for x, where a ≠ 0, we can apply the completing the square method to find a solution.
