Simplifying 4x2 + -9x + -2.5 = 0 Reorder the terms: -2.5 + -9x + 4x2 = 0 Solving -2.5 + -9x + 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'. -0.625 + -2.25x + x2 = 0 Move the constant term to the right: Add '0.625' to each side of the equation. -0.625 + -2.25x + 0.625 + x2 = 0 + 0.625 Reorder the terms: -0.625 + 0.625 + -2.25x + x2 = 0 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + -2.25x + x2 = 0 + 0.625 -2.25x + x2 = 0 + 0.625 Combine like terms: 0 + 0.625 = 0.625 -2.25x + x2 = 0.625 The x term is -2.25x. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25x + 1.265625 + x2 = 0.625 + 1.265625 Reorder the terms: 1.265625 + -2.25x + x2 = 0.625 + 1.265625 Combine like terms: 0.625 + 1.265625 = 1.890625 1.265625 + -2.25x + x2 = 1.890625 Factor a perfect square on the left side: (x + -1.125)(x + -1.125) = 1.890625 Calculate the square root of the right side: 1.375 Break this problem into two subproblems by setting (x + -1.125) equal to 1.375 and -1.375.Subproblem 1
x + -1.125 = 1.375 Simplifying x + -1.125 = 1.375 Reorder the terms: -1.125 + x = 1.375 Solving -1.125 + x = 1.375 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + x = 1.375 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + x = 1.375 + 1.125 x = 1.375 + 1.125 Combine like terms: 1.375 + 1.125 = 2.5 x = 2.5 Simplifying x = 2.5Subproblem 2
x + -1.125 = -1.375 Simplifying x + -1.125 = -1.375 Reorder the terms: -1.125 + x = -1.375 Solving -1.125 + x = -1.375 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + x = -1.375 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + x = -1.375 + 1.125 x = -1.375 + 1.125 Combine like terms: -1.375 + 1.125 = -0.25 x = -0.25 Simplifying x = -0.25Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.5, -0.25}
