Simplifying 5x2 + -2x + -15 + 6 = 0 Reorder the terms: -15 + 6 + -2x + 5x2 = 0 Combine like terms: -15 + 6 = -9 -9 + -2x + 5x2 = 0 Solving -9 + -2x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.8 + -0.4x + x2 = 0 Move the constant term to the right: Add '1.8' to each side of the equation. -1.8 + -0.4x + 1.8 + x2 = 0 + 1.8 Reorder the terms: -1.8 + 1.8 + -0.4x + x2 = 0 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + -0.4x + x2 = 0 + 1.8 -0.4x + x2 = 0 + 1.8 Combine like terms: 0 + 1.8 = 1.8 -0.4x + x2 = 1.8 The x term is -0.4x. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4x + 0.04 + x2 = 1.8 + 0.04 Reorder the terms: 0.04 + -0.4x + x2 = 1.8 + 0.04 Combine like terms: 1.8 + 0.04 = 1.84 0.04 + -0.4x + x2 = 1.84 Factor a perfect square on the left side: (x + -0.2)(x + -0.2) = 1.84 Calculate the square root of the right side: 1.356465997 Break this problem into two subproblems by setting (x + -0.2) equal to 1.356465997 and -1.356465997.Subproblem 1
x + -0.2 = 1.356465997 Simplifying x + -0.2 = 1.356465997 Reorder the terms: -0.2 + x = 1.356465997 Solving -0.2 + x = 1.356465997 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + x = 1.356465997 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = 1.356465997 + 0.2 x = 1.356465997 + 0.2 Combine like terms: 1.356465997 + 0.2 = 1.556465997 x = 1.556465997 Simplifying x = 1.556465997Subproblem 2
x + -0.2 = -1.356465997 Simplifying x + -0.2 = -1.356465997 Reorder the terms: -0.2 + x = -1.356465997 Solving -0.2 + x = -1.356465997 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + x = -1.356465997 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = -1.356465997 + 0.2 x = -1.356465997 + 0.2 Combine like terms: -1.356465997 + 0.2 = -1.156465997 x = -1.156465997 Simplifying x = -1.156465997Solution
