Simplifying 4x + -4x2 + -0.3 = 0 Reorder the terms: -0.3 + 4x + -4x2 = 0 Solving -0.3 + 4x + -4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 0.075 + -1x + x2 = 0 Move the constant term to the right: Add '-0.075' to each side of the equation. 0.075 + -1x + -0.075 + x2 = 0 + -0.075 Reorder the terms: 0.075 + -0.075 + -1x + x2 = 0 + -0.075 Combine like terms: 0.075 + -0.075 = 0.000 0.000 + -1x + x2 = 0 + -0.075 -1x + x2 = 0 + -0.075 Combine like terms: 0 + -0.075 = -0.075 -1x + x2 = -0.075 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -0.075 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -0.075 + 0.25 Combine like terms: -0.075 + 0.25 = 0.175 0.25 + -1x + x2 = 0.175 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 0.175 Calculate the square root of the right side: 0.418330013 Break this problem into two subproblems by setting (x + -0.5) equal to 0.418330013 and -0.418330013.Subproblem 1
x + -0.5 = 0.418330013 Simplifying x + -0.5 = 0.418330013 Reorder the terms: -0.5 + x = 0.418330013 Solving -0.5 + x = 0.418330013 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 0.418330013 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 0.418330013 + 0.5 x = 0.418330013 + 0.5 Combine like terms: 0.418330013 + 0.5 = 0.918330013 x = 0.918330013 Simplifying x = 0.918330013Subproblem 2
x + -0.5 = -0.418330013 Simplifying x + -0.5 = -0.418330013 Reorder the terms: -0.5 + x = -0.418330013 Solving -0.5 + x = -0.418330013 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -0.418330013 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -0.418330013 + 0.5 x = -0.418330013 + 0.5 Combine like terms: -0.418330013 + 0.5 = 0.081669987 x = 0.081669987 Simplifying x = 0.081669987Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.918330013, 0.081669987}
