Simplifying x(-4x + -9) = -2 Reorder the terms: x(-9 + -4x) = -2 (-9 * x + -4x * x) = -2 (-9x + -4x2) = -2 Solving -9x + -4x2 = -2 Solving for variable 'x'. Reorder the terms: 2 + -9x + -4x2 = -2 + 2 Combine like terms: -2 + 2 = 0 2 + -9x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.5 + 2.25x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 2.25x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 2.25x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 2.25x + x2 = 0 + 0.5 2.25x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 2.25x + x2 = 0.5 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 = 0.5 + 1.265625 Reorder the terms: 1.265625 + 2.25x + x2 = 0.5 + 1.265625 Combine like terms: 0.5 + 1.265625 = 1.765625 1.265625 + 2.25x + x2 = 1.765625 Factor a perfect square on the left side: (x + 1.125)(x + 1.125) = 1.765625 Calculate the square root of the right side: 1.328768227 Break this problem into two subproblems by setting (x + 1.125) equal to 1.328768227 and -1.328768227.Subproblem 1
x + 1.125 = 1.328768227 Simplifying x + 1.125 = 1.328768227 Reorder the terms: 1.125 + x = 1.328768227 Solving 1.125 + x = 1.328768227 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 = 1.328768227 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = 1.328768227 + -1.125 x = 1.328768227 + -1.125 Combine like terms: 1.328768227 + -1.125 = 0.203768227 x = 0.203768227 Simplifying x = 0.203768227Subproblem 2
x + 1.125 = -1.328768227 Simplifying x + 1.125 = -1.328768227 Reorder the terms: 1.125 + x = -1.328768227 Solving 1.125 + x = -1.328768227 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 = -1.328768227 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = -1.328768227 + -1.125 x = -1.328768227 + -1.125 Combine like terms: -1.328768227 + -1.125 = -2.453768227 x = -2.453768227 Simplifying x = -2.453768227Solution
