Simplifying 1.1x + 0.2x2 + -5.5 = 0 Reorder the terms: -5.5 + 1.1x + 0.2x2 = 0 Solving -5.5 + 1.1x + 0.2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. -27.5 + 5.5x + x2 = 0 Move the constant term to the right: Add '27.5' to each side of the equation. -27.5 + 5.5x + 27.5 + x2 = 0 + 27.5 Reorder the terms: -27.5 + 27.5 + 5.5x + x2 = 0 + 27.5 Combine like terms: -27.5 + 27.5 = 0.0 0.0 + 5.5x + x2 = 0 + 27.5 5.5x + x2 = 0 + 27.5 Combine like terms: 0 + 27.5 = 27.5 5.5x + x2 = 27.5 The x term is 5.5x. Take half its coefficient (2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. 5.5x + 7.5625 + x2 = 27.5 + 7.5625 Reorder the terms: 7.5625 + 5.5x + x2 = 27.5 + 7.5625 Combine like terms: 27.5 + 7.5625 = 35.0625 7.5625 + 5.5x + x2 = 35.0625 Factor a perfect square on the left side: (x + 2.75)(x + 2.75) = 35.0625 Calculate the square root of the right side: 5.921359641 Break this problem into two subproblems by setting (x + 2.75) equal to 5.921359641 and -5.921359641.Subproblem 1
x + 2.75 = 5.921359641 Simplifying x + 2.75 = 5.921359641 Reorder the terms: 2.75 + x = 5.921359641 Solving 2.75 + x = 5.921359641 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.75' to each side of the equation. 2.75 + -2.75 + x = 5.921359641 + -2.75 Combine like terms: 2.75 + -2.75 = 0.00 0.00 + x = 5.921359641 + -2.75 x = 5.921359641 + -2.75 Combine like terms: 5.921359641 + -2.75 = 3.171359641 x = 3.171359641 Simplifying x = 3.171359641Subproblem 2
