Simplifying 2x2 + 10 + x = 82 Reorder the terms: 10 + x + 2x2 = 82 Solving 10 + x + 2x2 = 82 Solving for variable 'x'. Reorder the terms: 10 + -82 + x + 2x2 = 82 + -82 Combine like terms: 10 + -82 = -72 -72 + x + 2x2 = 82 + -82 Combine like terms: 82 + -82 = 0 -72 + x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -36 + 0.5x + x2 = 0 Move the constant term to the right: Add '36' to each side of the equation. -36 + 0.5x + 36 + x2 = 0 + 36 Reorder the terms: -36 + 36 + 0.5x + x2 = 0 + 36 Combine like terms: -36 + 36 = 0 0 + 0.5x + x2 = 0 + 36 0.5x + x2 = 0 + 36 Combine like terms: 0 + 36 = 36 0.5x + x2 = 36 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5x + 0.25 + x2 = 36 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = 36 + 0.25 Combine like terms: 36 + 0.25 = 36.25 0.25 + 0.5x + x2 = 36.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 36.25 Calculate the square root of the right side: 6.020797289 Break this problem into two subproblems by setting (x + 0.5) equal to 6.020797289 and -6.020797289.Subproblem 1
x + 0.5 = 6.020797289 Simplifying x + 0.5 = 6.020797289 Reorder the terms: 0.5 + x = 6.020797289 Solving 0.5 + x = 6.020797289 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 6.020797289 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 6.020797289 + -0.5 x = 6.020797289 + -0.5 Combine like terms: 6.020797289 + -0.5 = 5.520797289 x = 5.520797289 Simplifying x = 5.520797289Subproblem 2
x + 0.5 = -6.020797289 Simplifying x + 0.5 = -6.020797289 Reorder the terms: 0.5 + x = -6.020797289 Solving 0.5 + x = -6.020797289 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -6.020797289 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -6.020797289 + -0.5 x = -6.020797289 + -0.5 Combine like terms: -6.020797289 + -0.5 = -6.520797289 x = -6.520797289 Simplifying x = -6.520797289Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.520797289, -6.520797289}
