Simplifying 9.7 = -0.01x2 + 0.26x + 8.65 Reorder the terms: 9.7 = 8.65 + 0.26x + -0.01x2 Solving 9.7 = 8.65 + 0.26x + -0.01x2 Solving for variable 'x'. Combine like terms: 9.7 + -8.65 = 1.05 1.05 + -0.26x + 0.01x2 = 8.65 + 0.26x + -0.01x2 + -8.65 + -0.26x + 0.01x2 Reorder the terms: 1.05 + -0.26x + 0.01x2 = 8.65 + -8.65 + 0.26x + -0.26x + -0.01x2 + 0.01x2 Combine like terms: 8.65 + -8.65 = 0.00 1.05 + -0.26x + 0.01x2 = 0.00 + 0.26x + -0.26x + -0.01x2 + 0.01x2 1.05 + -0.26x + 0.01x2 = 0.26x + -0.26x + -0.01x2 + 0.01x2 Combine like terms: 0.26x + -0.26x = 0.00 1.05 + -0.26x + 0.01x2 = 0.00 + -0.01x2 + 0.01x2 1.05 + -0.26x + 0.01x2 = -0.01x2 + 0.01x2 Combine like terms: -0.01x2 + 0.01x2 = 0.00 1.05 + -0.26x + 0.01x2 = 0.00 Begin completing the square. Divide all terms by 0.01 the coefficient of the squared term: Divide each side by '0.01'. 105 + -26x + x2 = 0 Move the constant term to the right: Add '-105' to each side of the equation. 105 + -26x + -105 + x2 = 0 + -105 Reorder the terms: 105 + -105 + -26x + x2 = 0 + -105 Combine like terms: 105 + -105 = 0 0 + -26x + x2 = 0 + -105 -26x + x2 = 0 + -105 Combine like terms: 0 + -105 = -105 -26x + x2 = -105 The x term is -26x. Take half its coefficient (-13). Square it (169) and add it to both sides. Add '169' to each side of the equation. -26x + 169 + x2 = -105 + 169 Reorder the terms: 169 + -26x + x2 = -105 + 169 Combine like terms: -105 + 169 = 64 169 + -26x + x2 = 64 Factor a perfect square on the left side: (x + -13)(x + -13) = 64 Calculate the square root of the right side: 8 Break this problem into two subproblems by setting (x + -13) equal to 8 and -8.Subproblem 1
x + -13 = 8 Simplifying x + -13 = 8 Reorder the terms: -13 + x = 8 Solving -13 + x = 8 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + x = 8 + 13 Combine like terms: -13 + 13 = 0 0 + x = 8 + 13 x = 8 + 13 Combine like terms: 8 + 13 = 21 x = 21 Simplifying x = 21Subproblem 2
x + -13 = -8 Simplifying x + -13 = -8 Reorder the terms: -13 + x = -8 Solving -13 + x = -8 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + x = -8 + 13 Combine like terms: -13 + 13 = 0 0 + x = -8 + 13 x = -8 + 13 Combine like terms: -8 + 13 = 5 x = 5 Simplifying x = 5Solution
The solution to the problem is based on the solutions from the subproblems. x = {21, 5}
