Simplifying 5x2 + 54x + 81 = 0.6 Reorder the terms: 81 + 54x + 5x2 = 0.6 Solving 81 + 54x + 5x2 = 0.6 Solving for variable 'x'. Reorder the terms: 81 + -0.6 + 54x + 5x2 = 0.6 + -0.6 Combine like terms: 81 + -0.6 = 80.4 80.4 + 54x + 5x2 = 0.6 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 80.4 + 54x + 5x2 = 0.0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 16.08 + 10.8x + x2 = 0.0 Move the constant term to the right: Add '-16.08' to each side of the equation. 16.08 + 10.8x + -16.08 + x2 = 0.0 + -16.08 Reorder the terms: 16.08 + -16.08 + 10.8x + x2 = 0.0 + -16.08 Combine like terms: 16.08 + -16.08 = 0.00 0.00 + 10.8x + x2 = 0.0 + -16.08 10.8x + x2 = 0.0 + -16.08 Combine like terms: 0.0 + -16.08 = -16.08 10.8x + x2 = -16.08 The x term is 10.8x. Take half its coefficient (5.4). Square it (29.16) and add it to both sides. Add '29.16' to each side of the equation. 10.8x + 29.16 + x2 = -16.08 + 29.16 Reorder the terms: 29.16 + 10.8x + x2 = -16.08 + 29.16 Combine like terms: -16.08 + 29.16 = 13.08 29.16 + 10.8x + x2 = 13.08 Factor a perfect square on the left side: (x + 5.4)(x + 5.4) = 13.08 Calculate the square root of the right side: 3.616628264 Break this problem into two subproblems by setting (x + 5.4) equal to 3.616628264 and -3.616628264.Subproblem 1
x + 5.4 = 3.616628264 Simplifying x + 5.4 = 3.616628264 Reorder the terms: 5.4 + x = 3.616628264 Solving 5.4 + x = 3.616628264 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5.4' to each side of the equation. 5.4 + -5.4 + x = 3.616628264 + -5.4 Combine like terms: 5.4 + -5.4 = 0.0 0.0 + x = 3.616628264 + -5.4 x = 3.616628264 + -5.4 Combine like terms: 3.616628264 + -5.4 = -1.783371736 x = -1.783371736 Simplifying x = -1.783371736Subproblem 2
x + 5.4 = -3.616628264 Simplifying x + 5.4 = -3.616628264 Reorder the terms: 5.4 + x = -3.616628264 Solving 5.4 + x = -3.616628264 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5.4' to each side of the equation. 5.4 + -5.4 + x = -3.616628264 + -5.4 Combine like terms: 5.4 + -5.4 = 0.0 0.0 + x = -3.616628264 + -5.4 x = -3.616628264 + -5.4 Combine like terms: -3.616628264 + -5.4 = -9.016628264 x = -9.016628264 Simplifying x = -9.016628264Solution
