Simplifying x2 + 2x + -1.35 = 0 Reorder the terms: -1.35 + 2x + x2 = 0 Solving -1.35 + 2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1.35' to each side of the equation. -1.35 + 2x + 1.35 + x2 = 0 + 1.35 Reorder the terms: -1.35 + 1.35 + 2x + x2 = 0 + 1.35 Combine like terms: -1.35 + 1.35 = 0.00 0.00 + 2x + x2 = 0 + 1.35 2x + x2 = 0 + 1.35 Combine like terms: 0 + 1.35 = 1.35 2x + x2 = 1.35 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 1.35 + 1 Reorder the terms: 1 + 2x + x2 = 1.35 + 1 Combine like terms: 1.35 + 1 = 2.35 1 + 2x + x2 = 2.35 Factor a perfect square on the left side: (x + 1)(x + 1) = 2.35 Calculate the square root of the right side: 1.532970972 Break this problem into two subproblems by setting (x + 1) equal to 1.532970972 and -1.532970972.Subproblem 1
x + 1 = 1.532970972 Simplifying x + 1 = 1.532970972 Reorder the terms: 1 + x = 1.532970972 Solving 1 + x = 1.532970972 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 1.532970972 + -1 Combine like terms: 1 + -1 = 0 0 + x = 1.532970972 + -1 x = 1.532970972 + -1 Combine like terms: 1.532970972 + -1 = 0.532970972 x = 0.532970972 Simplifying x = 0.532970972Subproblem 2
x + 1 = -1.532970972 Simplifying x + 1 = -1.532970972 Reorder the terms: 1 + x = -1.532970972 Solving 1 + x = -1.532970972 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -1.532970972 + -1 Combine like terms: 1 + -1 = 0 0 + x = -1.532970972 + -1 x = -1.532970972 + -1 Combine like terms: -1.532970972 + -1 = -2.532970972 x = -2.532970972 Simplifying x = -2.532970972Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.532970972, -2.532970972}
