Simplifying x2 + 1.80x + -18.29 = 0 Reorder the terms: -18.29 + 1.80x + x2 = 0 Solving -18.29 + 1.80x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '18.29' to each side of the equation. -18.29 + 1.80x + 18.29 + x2 = 0 + 18.29 Reorder the terms: -18.29 + 18.29 + 1.80x + x2 = 0 + 18.29 Combine like terms: -18.29 + 18.29 = 0.00 0.00 + 1.80x + x2 = 0 + 18.29 1.80x + x2 = 0 + 18.29 Combine like terms: 0 + 18.29 = 18.29 1.80x + x2 = 18.29 The x term is 1.80x. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.80x + 0.81 + x2 = 18.29 + 0.81 Reorder the terms: 0.81 + 1.80x + x2 = 18.29 + 0.81 Combine like terms: 18.29 + 0.81 = 19.1 0.81 + 1.80x + x2 = 19.1 Factor a perfect square on the left side: (x + 0.9)(x + 0.9) = 19.1 Calculate the square root of the right side: 4.370354677 Break this problem into two subproblems by setting (x + 0.9) equal to 4.370354677 and -4.370354677.Subproblem 1
x + 0.9 = 4.370354677 Simplifying x + 0.9 = 4.370354677 Reorder the terms: 0.9 + x = 4.370354677 Solving 0.9 + x = 4.370354677 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = 4.370354677 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = 4.370354677 + -0.9 x = 4.370354677 + -0.9 Combine like terms: 4.370354677 + -0.9 = 3.470354677 x = 3.470354677 Simplifying x = 3.470354677Subproblem 2
x + 0.9 = -4.370354677 Simplifying x + 0.9 = -4.370354677 Reorder the terms: 0.9 + x = -4.370354677 Solving 0.9 + x = -4.370354677 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = -4.370354677 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = -4.370354677 + -0.9 x = -4.370354677 + -0.9 Combine like terms: -4.370354677 + -0.9 = -5.270354677 x = -5.270354677 Simplifying x = -5.270354677Solution
