Simplifying 4x2 + -24x + -246 = 0 Reorder the terms: -246 + -24x + 4x2 = 0 Solving -246 + -24x + 4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-123 + -12x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-123 + -12x + 2x2)' equal to zero and attempt to solve: Simplifying -123 + -12x + 2x2 = 0 Solving -123 + -12x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -61.5 + -6x + x2 = 0 Move the constant term to the right: Add '61.5' to each side of the equation. -61.5 + -6x + 61.5 + x2 = 0 + 61.5 Reorder the terms: -61.5 + 61.5 + -6x + x2 = 0 + 61.5 Combine like terms: -61.5 + 61.5 = 0.0 0.0 + -6x + x2 = 0 + 61.5 -6x + x2 = 0 + 61.5 Combine like terms: 0 + 61.5 = 61.5 -6x + x2 = 61.5 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = 61.5 + 9 Reorder the terms: 9 + -6x + x2 = 61.5 + 9 Combine like terms: 61.5 + 9 = 70.5 9 + -6x + x2 = 70.5 Factor a perfect square on the left side: (x + -3)(x + -3) = 70.5 Calculate the square root of the right side: 8.396427812 Break this problem into two subproblems by setting (x + -3) equal to 8.396427812 and -8.396427812.Subproblem 1
x + -3 = 8.396427812 Simplifying x + -3 = 8.396427812 Reorder the terms: -3 + x = 8.396427812 Solving -3 + x = 8.396427812 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 8.396427812 + 3 Combine like terms: -3 + 3 = 0 0 + x = 8.396427812 + 3 x = 8.396427812 + 3 Combine like terms: 8.396427812 + 3 = 11.396427812 x = 11.396427812 Simplifying x = 11.396427812Subproblem 2
x + -3 = -8.396427812 Simplifying x + -3 = -8.396427812 Reorder the terms: -3 + x = -8.396427812 Solving -3 + x = -8.396427812 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = -8.396427812 + 3 Combine like terms: -3 + 3 = 0 0 + x = -8.396427812 + 3 x = -8.396427812 + 3 Combine like terms: -8.396427812 + 3 = -5.396427812 x = -5.396427812 Simplifying x = -5.396427812Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.396427812, -5.396427812}Solution
x = {11.396427812, -5.396427812}
