Simplifying -0.8x2 + 14.4x + 2 = 0 Reorder the terms: 2 + 14.4x + -0.8x2 = 0 Solving 2 + 14.4x + -0.8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.8 the coefficient of the squared term: Divide each side by '-0.8'. -2.5 + -18x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + -18x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + -18x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + -18x + x2 = 0 + 2.5 -18x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 -18x + x2 = 2.5 The x term is -18x. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18x + 81 + x2 = 2.5 + 81 Reorder the terms: 81 + -18x + x2 = 2.5 + 81 Combine like terms: 2.5 + 81 = 83.5 81 + -18x + x2 = 83.5 Factor a perfect square on the left side: (x + -9)(x + -9) = 83.5 Calculate the square root of the right side: 9.137833441 Break this problem into two subproblems by setting (x + -9) equal to 9.137833441 and -9.137833441.Subproblem 1
x + -9 = 9.137833441 Simplifying x + -9 = 9.137833441 Reorder the terms: -9 + x = 9.137833441 Solving -9 + x = 9.137833441 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = 9.137833441 + 9 Combine like terms: -9 + 9 = 0 0 + x = 9.137833441 + 9 x = 9.137833441 + 9 Combine like terms: 9.137833441 + 9 = 18.137833441 x = 18.137833441 Simplifying x = 18.137833441Subproblem 2
x + -9 = -9.137833441 Simplifying x + -9 = -9.137833441 Reorder the terms: -9 + x = -9.137833441 Solving -9 + x = -9.137833441 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = -9.137833441 + 9 Combine like terms: -9 + 9 = 0 0 + x = -9.137833441 + 9 x = -9.137833441 + 9 Combine like terms: -9.137833441 + 9 = -0.137833441 x = -0.137833441 Simplifying x = -0.137833441Solution
The solution to the problem is based on the solutions from the subproblems. x = {18.137833441, -0.137833441}
