Simplifying 0.5x2 + 1.1x + -65 = 0 Reorder the terms: -65 + 1.1x + 0.5x2 = 0 Solving -65 + 1.1x + 0.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. -130 + 2.2x + x2 = 0 Move the constant term to the right: Add '130' to each side of the equation. -130 + 2.2x + 130 + x2 = 0 + 130 Reorder the terms: -130 + 130 + 2.2x + x2 = 0 + 130 Combine like terms: -130 + 130 = 0 0 + 2.2x + x2 = 0 + 130 2.2x + x2 = 0 + 130 Combine like terms: 0 + 130 = 130 2.2x + x2 = 130 The x term is 2.2x. Take half its coefficient (1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. 2.2x + 1.21 + x2 = 130 + 1.21 Reorder the terms: 1.21 + 2.2x + x2 = 130 + 1.21 Combine like terms: 130 + 1.21 = 131.21 1.21 + 2.2x + x2 = 131.21 Factor a perfect square on the left side: (x + 1.1)(x + 1.1) = 131.21 Calculate the square root of the right side: 11.454693361 Break this problem into two subproblems by setting (x + 1.1) equal to 11.454693361 and -11.454693361.Subproblem 1
x + 1.1 = 11.454693361 Simplifying x + 1.1 = 11.454693361 Reorder the terms: 1.1 + x = 11.454693361 Solving 1.1 + x = 11.454693361 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + x = 11.454693361 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + x = 11.454693361 + -1.1 x = 11.454693361 + -1.1 Combine like terms: 11.454693361 + -1.1 = 10.354693361 x = 10.354693361 Simplifying x = 10.354693361Subproblem 2
x + 1.1 = -11.454693361 Simplifying x + 1.1 = -11.454693361 Reorder the terms: 1.1 + x = -11.454693361 Solving 1.1 + x = -11.454693361 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + x = -11.454693361 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + x = -11.454693361 + -1.1 x = -11.454693361 + -1.1 Combine like terms: -11.454693361 + -1.1 = -12.554693361 x = -12.554693361 Simplifying x = -12.554693361Solution
