Simplifying 8x2 + -6x + -17 = 3x2 Reorder the terms: -17 + -6x + 8x2 = 3x2 Solving -17 + -6x + 8x2 = 3x2 Solving for variable 'x'. Combine like terms: 8x2 + -3x2 = 5x2 -17 + -6x + 5x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -17 + -6x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -3.4 + -1.2x + x2 = 0 Move the constant term to the right: Add '3.4' to each side of the equation. -3.4 + -1.2x + 3.4 + x2 = 0 + 3.4 Reorder the terms: -3.4 + 3.4 + -1.2x + x2 = 0 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + -1.2x + x2 = 0 + 3.4 -1.2x + x2 = 0 + 3.4 Combine like terms: 0 + 3.4 = 3.4 -1.2x + x2 = 3.4 The x term is -1.2x. Take half its coefficient (-0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. -1.2x + 0.36 + x2 = 3.4 + 0.36 Reorder the terms: 0.36 + -1.2x + x2 = 3.4 + 0.36 Combine like terms: 3.4 + 0.36 = 3.76 0.36 + -1.2x + x2 = 3.76 Factor a perfect square on the left side: (x + -0.6)(x + -0.6) = 3.76 Calculate the square root of the right side: 1.939071943 Break this problem into two subproblems by setting (x + -0.6) equal to 1.939071943 and -1.939071943.Subproblem 1
x + -0.6 = 1.939071943 Simplifying x + -0.6 = 1.939071943 Reorder the terms: -0.6 + x = 1.939071943 Solving -0.6 + x = 1.939071943 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + x = 1.939071943 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + x = 1.939071943 + 0.6 x = 1.939071943 + 0.6 Combine like terms: 1.939071943 + 0.6 = 2.539071943 x = 2.539071943 Simplifying x = 2.539071943Subproblem 2
x + -0.6 = -1.939071943 Simplifying x + -0.6 = -1.939071943 Reorder the terms: -0.6 + x = -1.939071943 Solving -0.6 + x = -1.939071943 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + x = -1.939071943 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + x = -1.939071943 + 0.6 x = -1.939071943 + 0.6 Combine like terms: -1.939071943 + 0.6 = -1.339071943 x = -1.339071943 Simplifying x = -1.339071943Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.539071943, -1.339071943}
