Simplifying -2x2 + -24x + 1 = 0 Reorder the terms: 1 + -24x + -2x2 = 0 Solving 1 + -24x + -2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -0.5 + 12x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 12x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 12x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 12x + x2 = 0 + 0.5 12x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 12x + x2 = 0.5 The x term is 12x. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12x + 36 + x2 = 0.5 + 36 Reorder the terms: 36 + 12x + x2 = 0.5 + 36 Combine like terms: 0.5 + 36 = 36.5 36 + 12x + x2 = 36.5 Factor a perfect square on the left side: (x + 6)(x + 6) = 36.5 Calculate the square root of the right side: 6.041522987 Break this problem into two subproblems by setting (x + 6) equal to 6.041522987 and -6.041522987.Subproblem 1
x + 6 = 6.041522987 Simplifying x + 6 = 6.041522987 Reorder the terms: 6 + x = 6.041522987 Solving 6 + x = 6.041522987 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = 6.041522987 + -6 Combine like terms: 6 + -6 = 0 0 + x = 6.041522987 + -6 x = 6.041522987 + -6 Combine like terms: 6.041522987 + -6 = 0.041522987 x = 0.041522987 Simplifying x = 0.041522987Subproblem 2
x + 6 = -6.041522987 Simplifying x + 6 = -6.041522987 Reorder the terms: 6 + x = -6.041522987 Solving 6 + x = -6.041522987 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = -6.041522987 + -6 Combine like terms: 6 + -6 = 0 0 + x = -6.041522987 + -6 x = -6.041522987 + -6 Combine like terms: -6.041522987 + -6 = -12.041522987 x = -12.041522987 Simplifying x = -12.041522987Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.041522987, -12.041522987}
