Simplifying 54 = -0.8x2 + 14.4x + 2 Reorder the terms: 54 = 2 + 14.4x + -0.8x2 Solving 54 = 2 + 14.4x + -0.8x2 Solving for variable 'x'. Combine like terms: 54 + -2 = 52 52 + -14.4x + 0.8x2 = 2 + 14.4x + -0.8x2 + -2 + -14.4x + 0.8x2 Reorder the terms: 52 + -14.4x + 0.8x2 = 2 + -2 + 14.4x + -14.4x + -0.8x2 + 0.8x2 Combine like terms: 2 + -2 = 0 52 + -14.4x + 0.8x2 = 0 + 14.4x + -14.4x + -0.8x2 + 0.8x2 52 + -14.4x + 0.8x2 = 14.4x + -14.4x + -0.8x2 + 0.8x2 Combine like terms: 14.4x + -14.4x = 0.0 52 + -14.4x + 0.8x2 = 0.0 + -0.8x2 + 0.8x2 52 + -14.4x + 0.8x2 = -0.8x2 + 0.8x2 Combine like terms: -0.8x2 + 0.8x2 = 0.0 52 + -14.4x + 0.8x2 = 0.0 Begin completing the square. Divide all terms by 0.8 the coefficient of the squared term: Divide each side by '0.8'. 65 + -18x + x2 = 0 Move the constant term to the right: Add '-65' to each side of the equation. 65 + -18x + -65 + x2 = 0 + -65 Reorder the terms: 65 + -65 + -18x + x2 = 0 + -65 Combine like terms: 65 + -65 = 0 0 + -18x + x2 = 0 + -65 -18x + x2 = 0 + -65 Combine like terms: 0 + -65 = -65 -18x + x2 = -65 The x term is -18x. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18x + 81 + x2 = -65 + 81 Reorder the terms: 81 + -18x + x2 = -65 + 81 Combine like terms: -65 + 81 = 16 81 + -18x + x2 = 16 Factor a perfect square on the left side: (x + -9)(x + -9) = 16 Calculate the square root of the right side: 4 Break this problem into two subproblems by setting (x + -9) equal to 4 and -4.Subproblem 1
x + -9 = 4 Simplifying x + -9 = 4 Reorder the terms: -9 + x = 4 Solving -9 + x = 4 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = 4 + 9 Combine like terms: -9 + 9 = 0 0 + x = 4 + 9 x = 4 + 9 Combine like terms: 4 + 9 = 13 x = 13 Simplifying x = 13Subproblem 2
x + -9 = -4 Simplifying x + -9 = -4 Reorder the terms: -9 + x = -4 Solving -9 + x = -4 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = -4 + 9 Combine like terms: -9 + 9 = 0 0 + x = -4 + 9 x = -4 + 9 Combine like terms: -4 + 9 = 5 x = 5 Simplifying x = 5Solution
The solution to the problem is based on the solutions from the subproblems. x = {13, 5}
