Add 16 to both sides of the equation : On the right hand side we have : Complete the Square x^2+8x+. Add this number to both sides of the original equation: (x2 + 8x + 16) −2 = 16. According to the Quadratic Formula, x , the solution for Ax 2 +Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by : Solve x^2-8x-33=0 | Microsoft Math Solver. So the coefficient of x is -8. When we complete the square we want to end up with a quadratic that can be factored in the form (x+a) 2 or (x-a) 2. As an example let's complete the square for this quadratic equation: 2x2 − 12x + 7 = 0 2 x 2 − 12 x + 7 = 0. Subtracting 15 from itself leaves 0. For example, enter 3x+2=14 into the text box to get a step-by-step explanation of how to solve 3x+2=14. Add 10 10 to both sides of the equation. Tap for more steps 16 16. Solve Using the Quadratic Formula x^2-8x-20=0. Subtract 12 12 from both sides of the equation. Tap for more steps (x−5)(x− 3) = 0 ( x - 5) ( x - 3) = 0. Solve by Completing the Square x^2-8x+6=0. How do you factor and solve x2 + 8x = 0?
