Simplifying 5x2 + 2x + -54 = 0 Reorder the terms: -54 + 2x + 5x2 = 0 Solving -54 + 2x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -10.8 + 0.4x + x2 = 0 Move the constant term to the right: Add '10.8' to each side of the equation. -10.8 + 0.4x + 10.8 + x2 = 0 + 10.8 Reorder the terms: -10.8 + 10.8 + 0.4x + x2 = 0 + 10.8 Combine like terms: -10.8 + 10.8 = 0.0 0.0 + 0.4x + x2 = 0 + 10.8 0.4x + x2 = 0 + 10.8 Combine like terms: 0 + 10.8 = 10.8 0.4x + x2 = 10.8 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = 10.8 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = 10.8 + 0.04 Combine like terms: 10.8 + 0.04 = 10.84 0.04 + 0.4x + x2 = 10.84 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = 10.84 Calculate the square root of the right side: 3.292415527 Break this problem into two subproblems by setting (x + 0.2) equal to 3.292415527 and -3.292415527.Subproblem 1
x + 0.2 = 3.292415527 Simplifying x + 0.2 = 3.292415527 Reorder the terms: 0.2 + x = 3.292415527 Solving 0.2 + x = 3.292415527 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = 3.292415527 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = 3.292415527 + -0.2 x = 3.292415527 + -0.2 Combine like terms: 3.292415527 + -0.2 = 3.092415527 x = 3.092415527 Simplifying x = 3.092415527Subproblem 2
x + 0.2 = -3.292415527 Simplifying x + 0.2 = -3.292415527 Reorder the terms: 0.2 + x = -3.292415527 Solving 0.2 + x = -3.292415527 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = -3.292415527 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = -3.292415527 + -0.2 x = -3.292415527 + -0.2 Combine like terms: -3.292415527 + -0.2 = -3.492415527 x = -3.492415527 Simplifying x = -3.492415527Solution
