Simplifying 2x + 2x2 + 2 = 19 Reorder the terms: 2 + 2x + 2x2 = 19 Solving 2 + 2x + 2x2 = 19 Solving for variable 'x'. Reorder the terms: 2 + -19 + 2x + 2x2 = 19 + -19 Combine like terms: 2 + -19 = -17 -17 + 2x + 2x2 = 19 + -19 Combine like terms: 19 + -19 = 0 -17 + 2x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -8.5 + x + x2 = 0 Move the constant term to the right: Add '8.5' to each side of the equation. -8.5 + x + 8.5 + x2 = 0 + 8.5 Reorder the terms: -8.5 + 8.5 + x + x2 = 0 + 8.5 Combine like terms: -8.5 + 8.5 = 0.0 0.0 + x + x2 = 0 + 8.5 x + x2 = 0 + 8.5 Combine like terms: 0 + 8.5 = 8.5 x + x2 = 8.5 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. + 0.25 + x2 = 8.5 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 8.5 + 0.25 Combine like terms: 8.5 + 0.25 = 8.75 1.25 + x2 = 8.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 8.75 Calculate the square root of the right side: 2.958039892 Break this problem into two subproblems by setting (x + 0.5) equal to 2.958039892 and -2.958039892.Subproblem 1
x + 0.5 = 2.958039892 Simplifying x + 0.5 = 2.958039892 Reorder the terms: 0.5 + x = 2.958039892 Solving 0.5 + x = 2.958039892 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 = 2.958039892 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 2.958039892 + -0.5 x = 2.958039892 + -0.5 Combine like terms: 2.958039892 + -0.5 = 2.458039892 x = 2.458039892 Simplifying x = 2.458039892Subproblem 2
x + 0.5 = -2.958039892 Simplifying x + 0.5 = -2.958039892 Reorder the terms: 0.5 + x = -2.958039892 Solving 0.5 + x = -2.958039892 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 = -2.958039892 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -2.958039892 + -0.5 x = -2.958039892 + -0.5 Combine like terms: -2.958039892 + -0.5 = -3.458039892 x = -3.458039892 Simplifying x = -3.458039892Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.458039892, -3.458039892}
