Simplifying -4x2 + 6x + 5 = x Reorder the terms: 5 + 6x + -4x2 = x Solving 5 + 6x + -4x2 = x Solving for variable 'x'. Reorder the terms: 5 + 6x + -1x + -4x2 = x + -1x Combine like terms: 6x + -1x = 5x 5 + 5x + -4x2 = x + -1x Combine like terms: x + -1x = 0 5 + 5x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -1.25 + -1.25x + x2 = 0 Move the constant term to the right: Add '1.25' to each side of the equation. -1.25 + -1.25x + 1.25 + x2 = 0 + 1.25 Reorder the terms: -1.25 + 1.25 + -1.25x + x2 = 0 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + -1.25x + x2 = 0 + 1.25 -1.25x + x2 = 0 + 1.25 Combine like terms: 0 + 1.25 = 1.25 -1.25x + x2 = 1.25 The x term is -1.25x. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25x + 0.390625 + x2 = 1.25 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = 1.25 + 0.390625 Combine like terms: 1.25 + 0.390625 = 1.640625 0.390625 + -1.25x + x2 = 1.640625 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = 1.640625 Calculate the square root of the right side: 1.280868846 Break this problem into two subproblems by setting (x + -0.625) equal to 1.280868846 and -1.280868846.Subproblem 1
x + -0.625 = 1.280868846 Simplifying x + -0.625 = 1.280868846 Reorder the terms: -0.625 + x = 1.280868846 Solving -0.625 + x = 1.280868846 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = 1.280868846 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = 1.280868846 + 0.625 x = 1.280868846 + 0.625 Combine like terms: 1.280868846 + 0.625 = 1.905868846 x = 1.905868846 Simplifying x = 1.905868846Subproblem 2
x + -0.625 = -1.280868846 Simplifying x + -0.625 = -1.280868846 Reorder the terms: -0.625 + x = -1.280868846 Solving -0.625 + x = -1.280868846 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = -1.280868846 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = -1.280868846 + 0.625 x = -1.280868846 + 0.625 Combine like terms: -1.280868846 + 0.625 = -0.655868846 x = -0.655868846 Simplifying x = -0.655868846Solution
