Simplifying 5x * 4x = 56 + 2x Reorder the terms for easier multiplication: 5 * 4x * x = 56 + 2x Multiply 5 * 4 20x * x = 56 + 2x Multiply x * x 20x2 = 56 + 2x Solving 20x2 = 56 + 2x Solving for variable 'x'. Reorder the terms: -56 + -2x + 20x2 = 56 + 2x + -56 + -2x Reorder the terms: -56 + -2x + 20x2 = 56 + -56 + 2x + -2x Combine like terms: 56 + -56 = 0 -56 + -2x + 20x2 = 0 + 2x + -2x -56 + -2x + 20x2 = 2x + -2x Combine like terms: 2x + -2x = 0 -56 + -2x + 20x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-28 + -1x + 10x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-28 + -1x + 10x2)' equal to zero and attempt to solve: Simplifying -28 + -1x + 10x2 = 0 Solving -28 + -1x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -2.8 + -0.1x + x2 = 0.0 Move the constant term to the right: Add '2.8' to each side of the equation. -2.8 + -0.1x + 2.8 + x2 = 0.0 + 2.8 Reorder the terms: -2.8 + 2.8 + -0.1x + x2 = 0.0 + 2.8 Combine like terms: -2.8 + 2.8 = 0.0 0.0 + -0.1x + x2 = 0.0 + 2.8 -0.1x + x2 = 0.0 + 2.8 Combine like terms: 0.0 + 2.8 = 2.8 -0.1x + x2 = 2.8 The x term is -0.1x. Take half its coefficient (-0.05). Square it (0.0025) and add it to both sides. Add '0.0025' to each side of the equation. -0.1x + 0.0025 + x2 = 2.8 + 0.0025 Reorder the terms: 0.0025 + -0.1x + x2 = 2.8 + 0.0025 Combine like terms: 2.8 + 0.0025 = 2.8025 0.0025 + -0.1x + x2 = 2.8025 Factor a perfect square on the left side: (x + -0.05)(x + -0.05) = 2.8025 Calculate the square root of the right side: 1.674066904 Break this problem into two subproblems by setting (x + -0.05) equal to 1.674066904 and -1.674066904.Subproblem 1
x + -0.05 = 1.674066904 Simplifying x + -0.05 = 1.674066904 Reorder the terms: -0.05 + x = 1.674066904 Solving -0.05 + x = 1.674066904 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.05' to each side of the equation. -0.05 + 0.05 + x = 1.674066904 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + x = 1.674066904 + 0.05 x = 1.674066904 + 0.05 Combine like terms: 1.674066904 + 0.05 = 1.724066904 x = 1.724066904 Simplifying x = 1.724066904Subproblem 2
x + -0.05 = -1.674066904 Simplifying x + -0.05 = -1.674066904 Reorder the terms: -0.05 + x = -1.674066904 Solving -0.05 + x = -1.674066904 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.05' to each side of the equation. -0.05 + 0.05 + x = -1.674066904 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + x = -1.674066904 + 0.05 x = -1.674066904 + 0.05 Combine like terms: -1.674066904 + 0.05 = -1.624066904 x = -1.624066904 Simplifying x = -1.624066904Solution
