Simplifying 2x2 + 2x = 157 Reorder the terms: 2x + 2x2 = 157 Solving 2x + 2x2 = 157 Solving for variable 'x'. Reorder the terms: -157 + 2x + 2x2 = 157 + -157 Combine like terms: 157 + -157 = 0 -157 + 2x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -78.5 + x + x2 = 0 Move the constant term to the right: Add '78.5' to each side of the equation. -78.5 + x + 78.5 + x2 = 0 + 78.5 Reorder the terms: -78.5 + 78.5 + x + x2 = 0 + 78.5 Combine like terms: -78.5 + 78.5 = 0.0 0.0 + x + x2 = 0 + 78.5 x + x2 = 0 + 78.5 Combine like terms: 0 + 78.5 = 78.5 x + x2 = 78.5 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 = 78.5 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 78.5 + 0.25 Combine like terms: 78.5 + 0.25 = 78.75 1.25 + x2 = 78.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 78.75 Calculate the square root of the right side: 8.874119675 Break this problem into two subproblems by setting (x + 0.5) equal to 8.874119675 and -8.874119675.Subproblem 1
x + 0.5 = 8.874119675 Simplifying x + 0.5 = 8.874119675 Reorder the terms: 0.5 + x = 8.874119675 Solving 0.5 + x = 8.874119675 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 = 8.874119675 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 8.874119675 + -0.5 x = 8.874119675 + -0.5 Combine like terms: 8.874119675 + -0.5 = 8.374119675 x = 8.374119675 Simplifying x = 8.374119675Subproblem 2
x + 0.5 = -8.874119675 Simplifying x + 0.5 = -8.874119675 Reorder the terms: 0.5 + x = -8.874119675 Solving 0.5 + x = -8.874119675 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 = -8.874119675 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -8.874119675 + -0.5 x = -8.874119675 + -0.5 Combine like terms: -8.874119675 + -0.5 = -9.374119675 x = -9.374119675 Simplifying x = -9.374119675Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.374119675, -9.374119675}
