Simplifying -2x2 + -9x + 14 = 0 Reorder the terms: 14 + -9x + -2x2 = 0 Solving 14 + -9x + -2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -7 + 4.5x + x2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + 4.5x + 7 + x2 = 0 + 7 Reorder the terms: -7 + 7 + 4.5x + x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 4.5x + x2 = 0 + 7 4.5x + x2 = 0 + 7 Combine like terms: 0 + 7 = 7 4.5x + x2 = 7 The x term is 4.5x. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5x + 5.0625 + x2 = 7 + 5.0625 Reorder the terms: 5.0625 + 4.5x + x2 = 7 + 5.0625 Combine like terms: 7 + 5.0625 = 12.0625 5.0625 + 4.5x + x2 = 12.0625 Factor a perfect square on the left side: (x + 2.25)(x + 2.25) = 12.0625 Calculate the square root of the right side: 3.473110997 Break this problem into two subproblems by setting (x + 2.25) equal to 3.473110997 and -3.473110997.Subproblem 1
x + 2.25 = 3.473110997 Simplifying x + 2.25 = 3.473110997 Reorder the terms: 2.25 + x = 3.473110997 Solving 2.25 + x = 3.473110997 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = 3.473110997 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = 3.473110997 + -2.25 x = 3.473110997 + -2.25 Combine like terms: 3.473110997 + -2.25 = 1.223110997 x = 1.223110997 Simplifying x = 1.223110997Subproblem 2
x + 2.25 = -3.473110997 Simplifying x + 2.25 = -3.473110997 Reorder the terms: 2.25 + x = -3.473110997 Solving 2.25 + x = -3.473110997 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = -3.473110997 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = -3.473110997 + -2.25 x = -3.473110997 + -2.25 Combine like terms: -3.473110997 + -2.25 = -5.723110997 x = -5.723110997 Simplifying x = -5.723110997Solution
