Simplifying 5 = 4x2 + -6x + 2 Reorder the terms: 5 = 2 + -6x + 4x2 Solving 5 = 2 + -6x + 4x2 Solving for variable 'x'. Combine like terms: 5 + -2 = 3 3 + 6x + -4x2 = 2 + -6x + 4x2 + -2 + 6x + -4x2 Reorder the terms: 3 + 6x + -4x2 = 2 + -2 + -6x + 6x + 4x2 + -4x2 Combine like terms: 2 + -2 = 0 3 + 6x + -4x2 = 0 + -6x + 6x + 4x2 + -4x2 3 + 6x + -4x2 = -6x + 6x + 4x2 + -4x2 Combine like terms: -6x + 6x = 0 3 + 6x + -4x2 = 0 + 4x2 + -4x2 3 + 6x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 3 + 6x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.75 + -1.5x + x2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + -1.5x + 0.75 + x2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + -1.5x + x2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + -1.5x + x2 = 0 + 0.75 -1.5x + x2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 -1.5x + x2 = 0.75 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 = 0.75 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 0.75 + 0.5625 Combine like terms: 0.75 + 0.5625 = 1.3125 0.5625 + -1.5x + x2 = 1.3125 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 1.3125 Calculate the square root of the right side: 1.145643924 Break this problem into two subproblems by setting (x + -0.75) equal to 1.145643924 and -1.145643924.Subproblem 1
x + -0.75 = 1.145643924 Simplifying x + -0.75 = 1.145643924 Reorder the terms: -0.75 + x = 1.145643924 Solving -0.75 + x = 1.145643924 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 = 1.145643924 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 1.145643924 + 0.75 x = 1.145643924 + 0.75 Combine like terms: 1.145643924 + 0.75 = 1.895643924 x = 1.895643924 Simplifying x = 1.895643924Subproblem 2
x + -0.75 = -1.145643924 Simplifying x + -0.75 = -1.145643924 Reorder the terms: -0.75 + x = -1.145643924 Solving -0.75 + x = -1.145643924 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 = -1.145643924 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -1.145643924 + 0.75 x = -1.145643924 + 0.75 Combine like terms: -1.145643924 + 0.75 = -0.395643924 x = -0.395643924 Simplifying x = -0.395643924Solution
