Simplifying 2x2 + x = 187 Reorder the terms: x + 2x2 = 187 Solving x + 2x2 = 187 Solving for variable 'x'. Reorder the terms: -187 + x + 2x2 = 187 + -187 Combine like terms: 187 + -187 = 0 -187 + x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -93.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '93.5' to each side of the equation. -93.5 + 0.5x + 93.5 + x2 = 0 + 93.5 Reorder the terms: -93.5 + 93.5 + 0.5x + x2 = 0 + 93.5 Combine like terms: -93.5 + 93.5 = 0.0 0.0 + 0.5x + x2 = 0 + 93.5 0.5x + x2 = 0 + 93.5 Combine like terms: 0 + 93.5 = 93.5 0.5x + x2 = 93.5 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. 0.5x + 0.25 + x2 = 93.5 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = 93.5 + 0.25 Combine like terms: 93.5 + 0.25 = 93.75 0.25 + 0.5x + x2 = 93.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 93.75 Calculate the square root of the right side: 9.682458366 Break this problem into two subproblems by setting (x + 0.5) equal to 9.682458366 and -9.682458366.Subproblem 1
x + 0.5 = 9.682458366 Simplifying x + 0.5 = 9.682458366 Reorder the terms: 0.5 + x = 9.682458366 Solving 0.5 + x = 9.682458366 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 = 9.682458366 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 9.682458366 + -0.5 x = 9.682458366 + -0.5 Combine like terms: 9.682458366 + -0.5 = 9.182458366 x = 9.182458366 Simplifying x = 9.182458366Subproblem 2
x + 0.5 = -9.682458366 Simplifying x + 0.5 = -9.682458366 Reorder the terms: 0.5 + x = -9.682458366 Solving 0.5 + x = -9.682458366 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 = -9.682458366 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -9.682458366 + -0.5 x = -9.682458366 + -0.5 Combine like terms: -9.682458366 + -0.5 = -10.182458366 x = -10.182458366 Simplifying x = -10.182458366Solution
