Simplifying 2x2 + -3x + -75 = 0 Reorder the terms: -75 + -3x + 2x2 = 0 Solving -75 + -3x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -37.5 + -1.5x + x2 = 0 Move the constant term to the right: Add '37.5' to each side of the equation. -37.5 + -1.5x + 37.5 + x2 = 0 + 37.5 Reorder the terms: -37.5 + 37.5 + -1.5x + x2 = 0 + 37.5 Combine like terms: -37.5 + 37.5 = 0.0 0.0 + -1.5x + x2 = 0 + 37.5 -1.5x + x2 = 0 + 37.5 Combine like terms: 0 + 37.5 = 37.5 -1.5x + x2 = 37.5 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 37.5 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 37.5 + 0.5625 Combine like terms: 37.5 + 0.5625 = 38.0625 0.5625 + -1.5x + x2 = 38.0625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 38.0625 Calculate the square root of the right side: 6.16948134 Break this problem into two subproblems by setting (x + -0.75) equal to 6.16948134 and -6.16948134.Subproblem 1
x + -0.75 = 6.16948134 Simplifying x + -0.75 = 6.16948134 Reorder the terms: -0.75 + x = 6.16948134 Solving -0.75 + x = 6.16948134 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 6.16948134 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 6.16948134 + 0.75 x = 6.16948134 + 0.75 Combine like terms: 6.16948134 + 0.75 = 6.91948134 x = 6.91948134 Simplifying x = 6.91948134Subproblem 2
x + -0.75 = -6.16948134 Simplifying x + -0.75 = -6.16948134 Reorder the terms: -0.75 + x = -6.16948134 Solving -0.75 + x = -6.16948134 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -6.16948134 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -6.16948134 + 0.75 x = -6.16948134 + 0.75 Combine like terms: -6.16948134 + 0.75 = -5.41948134 x = -5.41948134 Simplifying x = -5.41948134Solution
