Simplifying 5(x + -2) + x = 6(x + 3) * 4x Reorder the terms: 5(-2 + x) + x = 6(x + 3) * 4x (-2 * 5 + x * 5) + x = 6(x + 3) * 4x (-10 + 5x) + x = 6(x + 3) * 4x Combine like terms: 5x + x = 6x -10 + 6x = 6(x + 3) * 4x Reorder the terms: -10 + 6x = 6(3 + x) * 4x Reorder the terms for easier multiplication: -10 + 6x = 6 * 4x(3 + x) Multiply 6 * 4 -10 + 6x = 24x(3 + x) -10 + 6x = (3 * 24x + x * 24x) -10 + 6x = (72x + 24x2) Solving -10 + 6x = 72x + 24x2 Solving for variable 'x'. Combine like terms: 6x + -72x = -66x -10 + -66x + -24x2 = 72x + 24x2 + -72x + -24x2 Reorder the terms: -10 + -66x + -24x2 = 72x + -72x + 24x2 + -24x2 Combine like terms: 72x + -72x = 0 -10 + -66x + -24x2 = 0 + 24x2 + -24x2 -10 + -66x + -24x2 = 24x2 + -24x2 Combine like terms: 24x2 + -24x2 = 0 -10 + -66x + -24x2 = 0 Factor out the Greatest Common Factor (GCF), '-2'. -2(5 + 33x + 12x2) = 0 Ignore the factor -2.Subproblem 1
Set the factor '(5 + 33x + 12x2)' equal to zero and attempt to solve: Simplifying 5 + 33x + 12x2 = 0 Solving 5 + 33x + 12x2 = 0 Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. 0.4166666667 + 2.75x + x2 = 0 Move the constant term to the right: Add '-0.4166666667' to each side of the equation. 0.4166666667 + 2.75x + -0.4166666667 + x2 = 0 + -0.4166666667 Reorder the terms: 0.4166666667 + -0.4166666667 + 2.75x + x2 = 0 + -0.4166666667 Combine like terms: 0.4166666667 + -0.4166666667 = 0.0000000000 0.0000000000 + 2.75x + x2 = 0 + -0.4166666667 2.75x + x2 = 0 + -0.4166666667 Combine like terms: 0 + -0.4166666667 = -0.4166666667 2.75x + x2 = -0.4166666667 The x term is 2.75x. Take half its coefficient (1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. 2.75x + 1.890625 + x2 = -0.4166666667 + 1.890625 Reorder the terms: 1.890625 + 2.75x + x2 = -0.4166666667 + 1.890625 Combine like terms: -0.4166666667 + 1.890625 = 1.4739583333 1.890625 + 2.75x + x2 = 1.4739583333 Factor a perfect square on the left side: (x + 1.375)(x + 1.375) = 1.4739583333 Calculate the square root of the right side: 1.214066857 Break this problem into two subproblems by setting (x + 1.375) equal to 1.214066857 and -1.214066857.Subproblem 1
