Simplifying 6(4x + -3) * 2x = 70 Reorder the terms: 6(-3 + 4x) * 2x = 70 Reorder the terms for easier multiplication: 6 * 2x(-3 + 4x) = 70 Multiply 6 * 2 12x(-3 + 4x) = 70 (-3 * 12x + 4x * 12x) = 70 (-36x + 48x2) = 70 Solving -36x + 48x2 = 70 Solving for variable 'x'. Reorder the terms: -70 + -36x + 48x2 = 70 + -70 Combine like terms: 70 + -70 = 0 -70 + -36x + 48x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-35 + -18x + 24x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-35 + -18x + 24x2)' equal to zero and attempt to solve: Simplifying -35 + -18x + 24x2 = 0 Solving -35 + -18x + 24x2 = 0 Begin completing the square. Divide all terms by 24 the coefficient of the squared term: Divide each side by '24'. -1.458333333 + -0.75x + x2 = 0 Move the constant term to the right: Add '1.458333333' to each side of the equation. -1.458333333 + -0.75x + 1.458333333 + x2 = 0 + 1.458333333 Reorder the terms: -1.458333333 + 1.458333333 + -0.75x + x2 = 0 + 1.458333333 Combine like terms: -1.458333333 + 1.458333333 = 0.000000000 0.000000000 + -0.75x + x2 = 0 + 1.458333333 -0.75x + x2 = 0 + 1.458333333 Combine like terms: 0 + 1.458333333 = 1.458333333 -0.75x + x2 = 1.458333333 The x term is -0.75x. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75x + 0.140625 + x2 = 1.458333333 + 0.140625 Reorder the terms: 0.140625 + -0.75x + x2 = 1.458333333 + 0.140625 Combine like terms: 1.458333333 + 0.140625 = 1.598958333 0.140625 + -0.75x + x2 = 1.598958333 Factor a perfect square on the left side: (x + -0.375)(x + -0.375) = 1.598958333 Calculate the square root of the right side: 1.264499242 Break this problem into two subproblems by setting (x + -0.375) equal to 1.264499242 and -1.264499242.Subproblem 1
x + -0.375 = 1.264499242 Simplifying x + -0.375 = 1.264499242 Reorder the terms: -0.375 + x = 1.264499242 Solving -0.375 + x = 1.264499242 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + x = 1.264499242 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + x = 1.264499242 + 0.375 x = 1.264499242 + 0.375 Combine like terms: 1.264499242 + 0.375 = 1.639499242 x = 1.639499242 Simplifying x = 1.639499242Subproblem 2
x + -0.375 = -1.264499242 Simplifying x + -0.375 = -1.264499242 Reorder the terms: -0.375 + x = -1.264499242 Solving -0.375 + x = -1.264499242 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + x = -1.264499242 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + x = -1.264499242 + 0.375 x = -1.264499242 + 0.375 Combine like terms: -1.264499242 + 0.375 = -0.889499242 x = -0.889499242 Simplifying x = -0.889499242Solution
