Simplifying x2 + 0.3x + -1.80 = 0 Reorder the terms: -1.80 + 0.3x + x2 = 0 Solving -1.80 + 0.3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1.80' to each side of the equation. -1.80 + 0.3x + 1.80 + x2 = 0 + 1.80 Reorder the terms: -1.80 + 1.80 + 0.3x + x2 = 0 + 1.80 Combine like terms: -1.80 + 1.80 = 0.00 0.00 + 0.3x + x2 = 0 + 1.80 0.3x + x2 = 0 + 1.80 Combine like terms: 0 + 1.80 = 1.8 0.3x + x2 = 1.8 The x term is 0.3x. Take half its coefficient (0.15). Square it (0.0225) and add it to both sides. Add '0.0225' to each side of the equation. 0.3x + 0.0225 + x2 = 1.8 + 0.0225 Reorder the terms: 0.0225 + 0.3x + x2 = 1.8 + 0.0225 Combine like terms: 1.8 + 0.0225 = 1.8225 0.0225 + 0.3x + x2 = 1.8225 Factor a perfect square on the left side: (x + 0.15)(x + 0.15) = 1.8225 Calculate the square root of the right side: 1.35 Break this problem into two subproblems by setting (x + 0.15) equal to 1.35 and -1.35.Subproblem 1
x + 0.15 = 1.35 Simplifying x + 0.15 = 1.35 Reorder the terms: 0.15 + x = 1.35 Solving 0.15 + x = 1.35 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.15' to each side of the equation. 0.15 + -0.15 + x = 1.35 + -0.15 Combine like terms: 0.15 + -0.15 = 0.00 0.00 + x = 1.35 + -0.15 x = 1.35 + -0.15 Combine like terms: 1.35 + -0.15 = 1.2 x = 1.2 Simplifying x = 1.2Subproblem 2
x + 0.15 = -1.35 Simplifying x + 0.15 = -1.35 Reorder the terms: 0.15 + x = -1.35 Solving 0.15 + x = -1.35 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.15' to each side of the equation. 0.15 + -0.15 + x = -1.35 + -0.15 Combine like terms: 0.15 + -0.15 = 0.00 0.00 + x = -1.35 + -0.15 x = -1.35 + -0.15 Combine like terms: -1.35 + -0.15 = -1.5 x = -1.5 Simplifying x = -1.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.2, -1.5}
