Simplifying 3.35 = x2 + 2x Reorder the terms: 3.35 = 2x + x2 Solving 3.35 = 2x + x2 Solving for variable 'x'. Reorder the terms: 3.35 + -2x + -1x2 = 2x + -2x + x2 + -1x2 Combine like terms: 2x + -2x = 0 3.35 + -2x + -1x2 = 0 + x2 + -1x2 3.35 + -2x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 3.35 + -2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -3.35 + 2x + x2 = 0 Move the constant term to the right: Add '3.35' to each side of the equation. -3.35 + 2x + 3.35 + x2 = 0 + 3.35 Reorder the terms: -3.35 + 3.35 + 2x + x2 = 0 + 3.35 Combine like terms: -3.35 + 3.35 = 0.00 0.00 + 2x + x2 = 0 + 3.35 2x + x2 = 0 + 3.35 Combine like terms: 0 + 3.35 = 3.35 2x + x2 = 3.35 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 3.35 + 1 Reorder the terms: 1 + 2x + x2 = 3.35 + 1 Combine like terms: 3.35 + 1 = 4.35 1 + 2x + x2 = 4.35 Factor a perfect square on the left side: (x + 1)(x + 1) = 4.35 Calculate the square root of the right side: 2.085665361 Break this problem into two subproblems by setting (x + 1) equal to 2.085665361 and -2.085665361.Subproblem 1
x + 1 = 2.085665361 Simplifying x + 1 = 2.085665361 Reorder the terms: 1 + x = 2.085665361 Solving 1 + x = 2.085665361 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 2.085665361 + -1 Combine like terms: 1 + -1 = 0 0 + x = 2.085665361 + -1 x = 2.085665361 + -1 Combine like terms: 2.085665361 + -1 = 1.085665361 x = 1.085665361 Simplifying x = 1.085665361Subproblem 2
x + 1 = -2.085665361 Simplifying x + 1 = -2.085665361 Reorder the terms: 1 + x = -2.085665361 Solving 1 + x = -2.085665361 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -2.085665361 + -1 Combine like terms: 1 + -1 = 0 0 + x = -2.085665361 + -1 x = -2.085665361 + -1 Combine like terms: -2.085665361 + -1 = -3.085665361 x = -3.085665361 Simplifying x = -3.085665361Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.085665361, -3.085665361}
