Simplifying 4x2 + -8 = 6x Reorder the terms: -8 + 4x2 = 6x Solving -8 + 4x2 = 6x Solving for variable 'x'. Reorder the terms: -8 + -6x + 4x2 = 6x + -6x Combine like terms: 6x + -6x = 0 -8 + -6x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-4 + -3x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-4 + -3x + 2x2)' equal to zero and attempt to solve: Simplifying -4 + -3x + 2x2 = 0 Solving -4 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2 + -1.5x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + -1.5x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + -1.5x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1.5x + x2 = 0 + 2 -1.5x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -1.5x + x2 = 2 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 2 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 2 + 0.5625 Combine like terms: 2 + 0.5625 = 2.5625 0.5625 + -1.5x + x2 = 2.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 2.5625 Calculate the square root of the right side: 1.600781059 Break this problem into two subproblems by setting (x + -0.75) equal to 1.600781059 and -1.600781059.Subproblem 1
x + -0.75 = 1.600781059 Simplifying x + -0.75 = 1.600781059 Reorder the terms: -0.75 + x = 1.600781059 Solving -0.75 + x = 1.600781059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 1.600781059 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 1.600781059 + 0.75 x = 1.600781059 + 0.75 Combine like terms: 1.600781059 + 0.75 = 2.350781059 x = 2.350781059 Simplifying x = 2.350781059Subproblem 2
x + -0.75 = -1.600781059 Simplifying x + -0.75 = -1.600781059 Reorder the terms: -0.75 + x = -1.600781059 Solving -0.75 + x = -1.600781059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -1.600781059 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -1.600781059 + 0.75 x = -1.600781059 + 0.75 Combine like terms: -1.600781059 + 0.75 = -0.850781059 x = -0.850781059 Simplifying x = -0.850781059Solution
