Simplifying 2x2 = 9x + 40 Reorder the terms: 2x2 = 40 + 9x Solving 2x2 = 40 + 9x Solving for variable 'x'. Reorder the terms: -40 + -9x + 2x2 = 40 + 9x + -40 + -9x Reorder the terms: -40 + -9x + 2x2 = 40 + -40 + 9x + -9x Combine like terms: 40 + -40 = 0 -40 + -9x + 2x2 = 0 + 9x + -9x -40 + -9x + 2x2 = 9x + -9x Combine like terms: 9x + -9x = 0 -40 + -9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -20 + -4.5x + x2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + -4.5x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + -4.5x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -4.5x + x2 = 0 + 20 -4.5x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 -4.5x + x2 = 20 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = 20 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = 20 + 5.0625 Combine like terms: 20 + 5.0625 = 25.0625 5.0625 + -4.5x + x2 = 25.0625 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = 25.0625 Calculate the square root of the right side: 5.006246099 Break this problem into two subproblems by setting (x + -2.25) equal to 5.006246099 and -5.006246099.Subproblem 1
x + -2.25 = 5.006246099 Simplifying x + -2.25 = 5.006246099 Reorder the terms: -2.25 + x = 5.006246099 Solving -2.25 + x = 5.006246099 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + x = 5.006246099 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + x = 5.006246099 + 2.25 x = 5.006246099 + 2.25 Combine like terms: 5.006246099 + 2.25 = 7.256246099 x = 7.256246099 Simplifying x = 7.256246099Subproblem 2
x + -2.25 = -5.006246099 Simplifying x + -2.25 = -5.006246099 Reorder the terms: -2.25 + x = -5.006246099 Solving -2.25 + x = -5.006246099 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + x = -5.006246099 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + x = -5.006246099 + 2.25 x = -5.006246099 + 2.25 Combine like terms: -5.006246099 + 2.25 = -2.756246099 x = -2.756246099 Simplifying x = -2.756246099Solution
