Simplifying 0.2x2 + -0.3x + -3.5 = 0 Reorder the terms: -3.5 + -0.3x + 0.2x2 = 0 Solving -3.5 + -0.3x + 0.2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. -17.5 + -1.5x + x2 = 0 Move the constant term to the right: Add '17.5' to each side of the equation. -17.5 + -1.5x + 17.5 + x2 = 0 + 17.5 Reorder the terms: -17.5 + 17.5 + -1.5x + x2 = 0 + 17.5 Combine like terms: -17.5 + 17.5 = 0.0 0.0 + -1.5x + x2 = 0 + 17.5 -1.5x + x2 = 0 + 17.5 Combine like terms: 0 + 17.5 = 17.5 -1.5x + x2 = 17.5 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 = 17.5 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 17.5 + 0.5625 Combine like terms: 17.5 + 0.5625 = 18.0625 0.5625 + -1.5x + x2 = 18.0625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 18.0625 Calculate the square root of the right side: 4.25 Break this problem into two subproblems by setting (x + -0.75) equal to 4.25 and -4.25.Subproblem 1
x + -0.75 = 4.25 Simplifying x + -0.75 = 4.25 Reorder the terms: -0.75 + x = 4.25 Solving -0.75 + x = 4.25 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 = 4.25 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 4.25 + 0.75 x = 4.25 + 0.75 Combine like terms: 4.25 + 0.75 = 5 x = 5 Simplifying x = 5Subproblem 2
x + -0.75 = -4.25 Simplifying x + -0.75 = -4.25 Reorder the terms: -0.75 + x = -4.25 Solving -0.75 + x = -4.25 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 = -4.25 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -4.25 + 0.75 x = -4.25 + 0.75 Combine like terms: -4.25 + 0.75 = -3.5 x = -3.5 Simplifying x = -3.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {5, -3.5}
