Simplifying x2 + 1.44x + -0.22 = 0 Reorder the terms: -0.22 + 1.44x + x2 = 0 Solving -0.22 + 1.44x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.22' to each side of the equation. -0.22 + 1.44x + 0.22 + x2 = 0 + 0.22 Reorder the terms: -0.22 + 0.22 + 1.44x + x2 = 0 + 0.22 Combine like terms: -0.22 + 0.22 = 0.00 0.00 + 1.44x + x2 = 0 + 0.22 1.44x + x2 = 0 + 0.22 Combine like terms: 0 + 0.22 = 0.22 1.44x + x2 = 0.22 The x term is 1.44x. Take half its coefficient (0.72). Square it (0.5184) and add it to both sides. Add '0.5184' to each side of the equation. 1.44x + 0.5184 + x2 = 0.22 + 0.5184 Reorder the terms: 0.5184 + 1.44x + x2 = 0.22 + 0.5184 Combine like terms: 0.22 + 0.5184 = 0.7384 0.5184 + 1.44x + x2 = 0.7384 Factor a perfect square on the left side: (x + 0.72)(x + 0.72) = 0.7384 Calculate the square root of the right side: 0.859302042 Break this problem into two subproblems by setting (x + 0.72) equal to 0.859302042 and -0.859302042.Subproblem 1
x + 0.72 = 0.859302042 Simplifying x + 0.72 = 0.859302042 Reorder the terms: 0.72 + x = 0.859302042 Solving 0.72 + x = 0.859302042 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.72' to each side of the equation. 0.72 + -0.72 + x = 0.859302042 + -0.72 Combine like terms: 0.72 + -0.72 = 0.00 0.00 + x = 0.859302042 + -0.72 x = 0.859302042 + -0.72 Combine like terms: 0.859302042 + -0.72 = 0.139302042 x = 0.139302042 Simplifying x = 0.139302042Subproblem 2
x + 0.72 = -0.859302042 Simplifying x + 0.72 = -0.859302042 Reorder the terms: 0.72 + x = -0.859302042 Solving 0.72 + x = -0.859302042 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.72' to each side of the equation. 0.72 + -0.72 + x = -0.859302042 + -0.72 Combine like terms: 0.72 + -0.72 = 0.00 0.00 + x = -0.859302042 + -0.72 x = -0.859302042 + -0.72 Combine like terms: -0.859302042 + -0.72 = -1.579302042 x = -1.579302042 Simplifying x = -1.579302042Solution
