Simplifying 3x(x + -5) = 7x2 + -16 Reorder the terms: 3x(-5 + x) = 7x2 + -16 (-5 * 3x + x * 3x) = 7x2 + -16 (-15x + 3x2) = 7x2 + -16 Reorder the terms: -15x + 3x2 = -16 + 7x2 Solving -15x + 3x2 = -16 + 7x2 Solving for variable 'x'. Reorder the terms: 16 + -15x + 3x2 + -7x2 = -16 + 7x2 + 16 + -7x2 Combine like terms: 3x2 + -7x2 = -4x2 16 + -15x + -4x2 = -16 + 7x2 + 16 + -7x2 Reorder the terms: 16 + -15x + -4x2 = -16 + 16 + 7x2 + -7x2 Combine like terms: -16 + 16 = 0 16 + -15x + -4x2 = 0 + 7x2 + -7x2 16 + -15x + -4x2 = 7x2 + -7x2 Combine like terms: 7x2 + -7x2 = 0 16 + -15x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -4 + 3.75x + x2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + 3.75x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + 3.75x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 3.75x + x2 = 0 + 4 3.75x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 3.75x + x2 = 4 The x term is 3.75x. Take half its coefficient (1.875). Square it (3.515625) and add it to both sides. Add '3.515625' to each side of the equation. 3.75x + 3.515625 + x2 = 4 + 3.515625 Reorder the terms: 3.515625 + 3.75x + x2 = 4 + 3.515625 Combine like terms: 4 + 3.515625 = 7.515625 3.515625 + 3.75x + x2 = 7.515625 Factor a perfect square on the left side: (x + 1.875)(x + 1.875) = 7.515625 Calculate the square root of the right side: 2.741464025 Break this problem into two subproblems by setting (x + 1.875) equal to 2.741464025 and -2.741464025.Subproblem 1
x + 1.875 = 2.741464025 Simplifying x + 1.875 = 2.741464025 Reorder the terms: 1.875 + x = 2.741464025 Solving 1.875 + x = 2.741464025 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.875' to each side of the equation. 1.875 + -1.875 + x = 2.741464025 + -1.875 Combine like terms: 1.875 + -1.875 = 0.000 0.000 + x = 2.741464025 + -1.875 x = 2.741464025 + -1.875 Combine like terms: 2.741464025 + -1.875 = 0.866464025 x = 0.866464025 Simplifying x = 0.866464025Subproblem 2
x + 1.875 = -2.741464025 Simplifying x + 1.875 = -2.741464025 Reorder the terms: 1.875 + x = -2.741464025 Solving 1.875 + x = -2.741464025 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.875' to each side of the equation. 1.875 + -1.875 + x = -2.741464025 + -1.875 Combine like terms: 1.875 + -1.875 = 0.000 0.000 + x = -2.741464025 + -1.875 x = -2.741464025 + -1.875 Combine like terms: -2.741464025 + -1.875 = -4.616464025 x = -4.616464025 Simplifying x = -4.616464025Solution
