Simplifying 0 = -2x2 + 29x + -18 Reorder the terms: 0 = -18 + 29x + -2x2 Solving 0 = -18 + 29x + -2x2 Solving for variable 'x'. Combine like terms: 0 + 18 = 18 18 + -29x + 2x2 = -18 + 29x + -2x2 + 18 + -29x + 2x2 Reorder the terms: 18 + -29x + 2x2 = -18 + 18 + 29x + -29x + -2x2 + 2x2 Combine like terms: -18 + 18 = 0 18 + -29x + 2x2 = 0 + 29x + -29x + -2x2 + 2x2 18 + -29x + 2x2 = 29x + -29x + -2x2 + 2x2 Combine like terms: 29x + -29x = 0 18 + -29x + 2x2 = 0 + -2x2 + 2x2 18 + -29x + 2x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 18 + -29x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 9 + -14.5x + x2 = 0 Move the constant term to the right: Add '-9' to each side of the equation. 9 + -14.5x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -14.5x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -14.5x + x2 = 0 + -9 -14.5x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -14.5x + x2 = -9 The x term is -14.5x. Take half its coefficient (-7.25). Square it (52.5625) and add it to both sides. Add '52.5625' to each side of the equation. -14.5x + 52.5625 + x2 = -9 + 52.5625 Reorder the terms: 52.5625 + -14.5x + x2 = -9 + 52.5625 Combine like terms: -9 + 52.5625 = 43.5625 52.5625 + -14.5x + x2 = 43.5625 Factor a perfect square on the left side: (x + -7.25)(x + -7.25) = 43.5625 Calculate the square root of the right side: 6.600189391 Break this problem into two subproblems by setting (x + -7.25) equal to 6.600189391 and -6.600189391.Subproblem 1
x + -7.25 = 6.600189391 Simplifying x + -7.25 = 6.600189391 Reorder the terms: -7.25 + x = 6.600189391 Solving -7.25 + x = 6.600189391 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.25' to each side of the equation. -7.25 + 7.25 + x = 6.600189391 + 7.25 Combine like terms: -7.25 + 7.25 = 0.00 0.00 + x = 6.600189391 + 7.25 x = 6.600189391 + 7.25 Combine like terms: 6.600189391 + 7.25 = 13.850189391 x = 13.850189391 Simplifying x = 13.850189391Subproblem 2
x + -7.25 = -6.600189391 Simplifying x + -7.25 = -6.600189391 Reorder the terms: -7.25 + x = -6.600189391 Solving -7.25 + x = -6.600189391 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.25' to each side of the equation. -7.25 + 7.25 + x = -6.600189391 + 7.25 Combine like terms: -7.25 + 7.25 = 0.00 0.00 + x = -6.600189391 + 7.25 x = -6.600189391 + 7.25 Combine like terms: -6.600189391 + 7.25 = 0.649810609 x = 0.649810609 Simplifying x = 0.649810609Solution
