Begin completing the square. Divide all terms by -0.5 the coefficient of the squared term: Divide each side by '-0.5'. -5.2 + 2.7x + x2 = 0 Move the constant term to the right: Add '5.2' to each side of the equation. -5.2 + 2.7x + 5.2 + x2 = 0 + 5.2 Reorder the terms: -5.2 + 5.2 + 2.7x + x2 = 0 + 5.2 Combine like terms: -5.2 + 5.2 = 0.0 0.0 + 2.7x + x2 = 0 + 5.2 2.7x + x2 = 0 + 5.2 Combine like terms: 0 + 5.2 = 5.2 2.7x + x2 = 5.2 The x term is 2.7x. Take half its coefficient (1.35). Square it (1.8225) and add it to both sides. Add '1.8225' to each side of the equation. 2.7x + 1.8225 + x2 = 5.2 + 1.8225 Reorder the terms: 1.8225 + 2.7x + x2 = 5.2 + 1.8225 Combine like terms: 5.2 + 1.8225 = 7.0225 1.8225 + 2.7x + x2 = 7.0225 Factor a perfect square on the left side: (x + 1.35)(x + 1.35) = 7.0225 Calculate the square root of the right side: 2.65 Break this problem into two subproblems by setting (x + 1.35) equal to 2.65 and -2.65.Subproblem 1
x + 1.35 = 2.65 Simplifying x + 1.35 = 2.65 Reorder the terms: 1.35 + x = 2.65 Solving 1.35 + x = 2.65 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.35' to each side of the equation. 1.35 + -1.35 + x = 2.65 + -1.35 Combine like terms: 1.35 + -1.35 = 0.00 0.00 + x = 2.65 + -1.35 x = 2.65 + -1.35 Combine like terms: 2.65 + -1.35 = 1.3 x = 1.3 Simplifying x = 1.3Subproblem 2
x + 1.35 = -2.65 Simplifying x + 1.35 = -2.65 Reorder the terms: 1.35 + x = -2.65 Solving 1.35 + x = -2.65 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.35' to each side of the equation. 1.35 + -1.35 + x = -2.65 + -1.35 Combine like terms: 1.35 + -1.35 = 0.00 0.00 + x = -2.65 + -1.35 x = -2.65 + -1.35 Combine like terms: -2.65 + -1.35 = -4 x = -4 Simplifying x = -4Solution
