Algebra. Substitute the values a = 1 a = 1, b = 8 b = 8, and c = −12 c = - 12 into the quadratic formula and solve for x x. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. As an example let's complete the square for this quadratic equation: 2x2 − 12x + 7 = 0 2 x 2 − 12 x + 7 = 0. x2 − 8x − 4 = 0 x 2 - 8 x - 4 = 0. Substitute the values a = 1 a = 1, b = −8 b = - 8, and c = −9 c = - 9 into the quadratic formula and solve for x x. To use the direct factoring method, the equation must be in the form x^2+Bx+C=0. x2 + 8x = −12 x 2 + 8 x = - 12. en. Quadratic equations such as this one can be solved by a new direct factoring method that does not require guess work.3 Solving x 2-8x+25 = 0 by the Quadratic Formula ., < > ≤: ≥ ^ √: ⬅: : F _ ÷ | (* / ⌫ A: ↻: x: y = +-G
