Simplifying x + -3(3x + -3) = 2x(2x + -1) Reorder the terms: x + -3(-3 + 3x) = 2x(2x + -1) x + (-3 * -3 + 3x * -3) = 2x(2x + -1) x + (9 + -9x) = 2x(2x + -1) Reorder the terms: 9 + x + -9x = 2x(2x + -1) Combine like terms: x + -9x = -8x 9 + -8x = 2x(2x + -1) Reorder the terms: 9 + -8x = 2x(-1 + 2x) 9 + -8x = (-1 * 2x + 2x * 2x) 9 + -8x = (-2x + 4x2) Solving 9 + -8x = -2x + 4x2 Solving for variable 'x'. Combine like terms: -8x + 2x = -6x 9 + -6x + -4x2 = -2x + 4x2 + 2x + -4x2 Reorder the terms: 9 + -6x + -4x2 = -2x + 2x + 4x2 + -4x2 Combine like terms: -2x + 2x = 0 9 + -6x + -4x2 = 0 + 4x2 + -4x2 9 + -6x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 9 + -6x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -2.25 + 1.5x + x2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + 1.5x + 2.25 + x2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + 1.5x + x2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + 1.5x + x2 = 0 + 2.25 1.5x + x2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 1.5x + x2 = 2.25 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = 2.25 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 2.25 + 0.5625 Combine like terms: 2.25 + 0.5625 = 2.8125 0.5625 + 1.5x + x2 = 2.8125 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 2.8125 Calculate the square root of the right side: 1.677050983 Break this problem into two subproblems by setting (x + 0.75) equal to 1.677050983 and -1.677050983.Subproblem 1
x + 0.75 = 1.677050983 Simplifying x + 0.75 = 1.677050983 Reorder the terms: 0.75 + x = 1.677050983 Solving 0.75 + x = 1.677050983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = 1.677050983 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 1.677050983 + -0.75 x = 1.677050983 + -0.75 Combine like terms: 1.677050983 + -0.75 = 0.927050983 x = 0.927050983 Simplifying x = 0.927050983Subproblem 2
x + 0.75 = -1.677050983 Simplifying x + 0.75 = -1.677050983 Reorder the terms: 0.75 + x = -1.677050983 Solving 0.75 + x = -1.677050983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = -1.677050983 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -1.677050983 + -0.75 x = -1.677050983 + -0.75 Combine like terms: -1.677050983 + -0.75 = -2.427050983 x = -2.427050983 Simplifying x = -2.427050983Solution
