Simplifying 4x2 + -36x + 38.75 = 0 Reorder the terms: 38.75 + -36x + 4x2 = 0 Solving 38.75 + -36x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 9.6875 + -9x + x2 = 0 Move the constant term to the right: Add '-9.6875' to each side of the equation. 9.6875 + -9x + -9.6875 + x2 = 0 + -9.6875 Reorder the terms: 9.6875 + -9.6875 + -9x + x2 = 0 + -9.6875 Combine like terms: 9.6875 + -9.6875 = 0.0000 0.0000 + -9x + x2 = 0 + -9.6875 -9x + x2 = 0 + -9.6875 Combine like terms: 0 + -9.6875 = -9.6875 -9x + x2 = -9.6875 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = -9.6875 + 20.25 Reorder the terms: 20.25 + -9x + x2 = -9.6875 + 20.25 Combine like terms: -9.6875 + 20.25 = 10.5625 20.25 + -9x + x2 = 10.5625 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 10.5625 Calculate the square root of the right side: 3.25 Break this problem into two subproblems by setting (x + -4.5) equal to 3.25 and -3.25.Subproblem 1
x + -4.5 = 3.25 Simplifying x + -4.5 = 3.25 Reorder the terms: -4.5 + x = 3.25 Solving -4.5 + x = 3.25 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 3.25 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 3.25 + 4.5 x = 3.25 + 4.5 Combine like terms: 3.25 + 4.5 = 7.75 x = 7.75 Simplifying x = 7.75Subproblem 2
x + -4.5 = -3.25 Simplifying x + -4.5 = -3.25 Reorder the terms: -4.5 + x = -3.25 Solving -4.5 + x = -3.25 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = -3.25 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -3.25 + 4.5 x = -3.25 + 4.5 Combine like terms: -3.25 + 4.5 = 1.25 x = 1.25 Simplifying x = 1.25Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.75, 1.25}
