Simplifying 4x2 + -6 = -12x Reorder the terms: -6 + 4x2 = -12x Solving -6 + 4x2 = -12x Solving for variable 'x'. Reorder the terms: -6 + 12x + 4x2 = -12x + 12x Combine like terms: -12x + 12x = 0 -6 + 12x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-3 + 6x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-3 + 6x + 2x2)' equal to zero and attempt to solve: Simplifying -3 + 6x + 2x2 = 0 Solving -3 + 6x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + 3x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + 3x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + 3x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + 3x + x2 = 0 + 1.5 3x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 3x + x2 = 1.5 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 1.5 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 1.5 + 2.25 Combine like terms: 1.5 + 2.25 = 3.75 2.25 + 3x + x2 = 3.75 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (x + 1.5) equal to 1.936491673 and -1.936491673.Subproblem 1
x + 1.5 = 1.936491673 Simplifying x + 1.5 = 1.936491673 Reorder the terms: 1.5 + x = 1.936491673 Solving 1.5 + x = 1.936491673 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 1.936491673 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 1.936491673 + -1.5 x = 1.936491673 + -1.5 Combine like terms: 1.936491673 + -1.5 = 0.436491673 x = 0.436491673 Simplifying x = 0.436491673Subproblem 2
x + 1.5 = -1.936491673 Simplifying x + 1.5 = -1.936491673 Reorder the terms: 1.5 + x = -1.936491673 Solving 1.5 + x = -1.936491673 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -1.936491673 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -1.936491673 + -1.5 x = -1.936491673 + -1.5 Combine like terms: -1.936491673 + -1.5 = -3.436491673 x = -3.436491673 Simplifying x = -3.436491673Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.436491673, -3.436491673}Solution
x = {0.436491673, -3.436491673}
