Simplifying 12 + 2x + -4x2 = 3 Solving 12 + 2x + -4x2 = 3 Solving for variable 'x'. Reorder the terms: 12 + -3 + 2x + -4x2 = 3 + -3 Combine like terms: 12 + -3 = 9 9 + 2x + -4x2 = 3 + -3 Combine like terms: 3 + -3 = 0 9 + 2x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -2.25 + -0.5x + x2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + -0.5x + 2.25 + x2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + -0.5x + x2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + -0.5x + x2 = 0 + 2.25 -0.5x + x2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 -0.5x + x2 = 2.25 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 2.25 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 2.25 + 0.0625 Combine like terms: 2.25 + 0.0625 = 2.3125 0.0625 + -0.5x + x2 = 2.3125 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 2.3125 Calculate the square root of the right side: 1.520690633 Break this problem into two subproblems by setting (x + -0.25) equal to 1.520690633 and -1.520690633.Subproblem 1
x + -0.25 = 1.520690633 Simplifying x + -0.25 = 1.520690633 Reorder the terms: -0.25 + x = 1.520690633 Solving -0.25 + x = 1.520690633 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 1.520690633 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 1.520690633 + 0.25 x = 1.520690633 + 0.25 Combine like terms: 1.520690633 + 0.25 = 1.770690633 x = 1.770690633 Simplifying x = 1.770690633Subproblem 2
x + -0.25 = -1.520690633 Simplifying x + -0.25 = -1.520690633 Reorder the terms: -0.25 + x = -1.520690633 Solving -0.25 + x = -1.520690633 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -1.520690633 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -1.520690633 + 0.25 x = -1.520690633 + 0.25 Combine like terms: -1.520690633 + 0.25 = -1.270690633 x = -1.270690633 Simplifying x = -1.270690633Solution
