Simplifying 0 = 2x2 + -4x + -5.5 Reorder the terms: 0 = -5.5 + -4x + 2x2 Solving 0 = -5.5 + -4x + 2x2 Solving for variable 'x'. Combine like terms: 0 + 5.5 = 5.5 5.5 + 4x + -2x2 = -5.5 + -4x + 2x2 + 5.5 + 4x + -2x2 Reorder the terms: 5.5 + 4x + -2x2 = -5.5 + 5.5 + -4x + 4x + 2x2 + -2x2 Combine like terms: -5.5 + 5.5 = 0.0 5.5 + 4x + -2x2 = 0.0 + -4x + 4x + 2x2 + -2x2 5.5 + 4x + -2x2 = -4x + 4x + 2x2 + -2x2 Combine like terms: -4x + 4x = 0 5.5 + 4x + -2x2 = 0 + 2x2 + -2x2 5.5 + 4x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 5.5 + 4x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -2.75 + -2x + x2 = 0 Move the constant term to the right: Add '2.75' to each side of the equation. -2.75 + -2x + 2.75 + x2 = 0 + 2.75 Reorder the terms: -2.75 + 2.75 + -2x + x2 = 0 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + -2x + x2 = 0 + 2.75 -2x + x2 = 0 + 2.75 Combine like terms: 0 + 2.75 = 2.75 -2x + x2 = 2.75 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 = 2.75 + 1 Reorder the terms: 1 + -2x + x2 = 2.75 + 1 Combine like terms: 2.75 + 1 = 3.75 1 + -2x + x2 = 3.75 Factor a perfect square on the left side: (x + -1)(x + -1) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (x + -1) equal to 1.936491673 and -1.936491673.Subproblem 1
x + -1 = 1.936491673 Simplifying x + -1 = 1.936491673 Reorder the terms: -1 + x = 1.936491673 Solving -1 + x = 1.936491673 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 = 1.936491673 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.936491673 + 1 x = 1.936491673 + 1 Combine like terms: 1.936491673 + 1 = 2.936491673 x = 2.936491673 Simplifying x = 2.936491673Subproblem 2
x + -1 = -1.936491673 Simplifying x + -1 = -1.936491673 Reorder the terms: -1 + x = -1.936491673 Solving -1 + x = -1.936491673 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 = -1.936491673 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.936491673 + 1 x = -1.936491673 + 1 Combine like terms: -1.936491673 + 1 = -0.936491673 x = -0.936491673 Simplifying x = -0.936491673Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.936491673, -0.936491673}
