Simplifying 5x2 + -8x + -124 = 0 Reorder the terms: -124 + -8x + 5x2 = 0 Solving -124 + -8x + 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'. -24.8 + -1.6x + x2 = 0 Move the constant term to the right: Add '24.8' to each side of the equation. -24.8 + -1.6x + 24.8 + x2 = 0 + 24.8 Reorder the terms: -24.8 + 24.8 + -1.6x + x2 = 0 + 24.8 Combine like terms: -24.8 + 24.8 = 0.0 0.0 + -1.6x + x2 = 0 + 24.8 -1.6x + x2 = 0 + 24.8 Combine like terms: 0 + 24.8 = 24.8 -1.6x + x2 = 24.8 The x term is -1.6x. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6x + 0.64 + x2 = 24.8 + 0.64 Reorder the terms: 0.64 + -1.6x + x2 = 24.8 + 0.64 Combine like terms: 24.8 + 0.64 = 25.44 0.64 + -1.6x + x2 = 25.44 Factor a perfect square on the left side: (x + -0.8)(x + -0.8) = 25.44 Calculate the square root of the right side: 5.043808085 Break this problem into two subproblems by setting (x + -0.8) equal to 5.043808085 and -5.043808085.Subproblem 1
x + -0.8 = 5.043808085 Simplifying x + -0.8 = 5.043808085 Reorder the terms: -0.8 + x = 5.043808085 Solving -0.8 + x = 5.043808085 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = 5.043808085 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = 5.043808085 + 0.8 x = 5.043808085 + 0.8 Combine like terms: 5.043808085 + 0.8 = 5.843808085 x = 5.843808085 Simplifying x = 5.843808085Subproblem 2
x + -0.8 = -5.043808085 Simplifying x + -0.8 = -5.043808085 Reorder the terms: -0.8 + x = -5.043808085 Solving -0.8 + x = -5.043808085 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = -5.043808085 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = -5.043808085 + 0.8 x = -5.043808085 + 0.8 Combine like terms: -5.043808085 + 0.8 = -4.243808085 x = -4.243808085 Simplifying x = -4.243808085Solution
