Simplifying 6x2 + -81x + 12 = 0 Reorder the terms: 12 + -81x + 6x2 = 0 Solving 12 + -81x + 6x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(4 + -27x + 2x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(4 + -27x + 2x2)' equal to zero and attempt to solve: Simplifying 4 + -27x + 2x2 = 0 Solving 4 + -27x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2 + -13.5x + x2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -13.5x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + -13.5x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -13.5x + x2 = 0 + -2 -13.5x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -13.5x + x2 = -2 The x term is -13.5x. Take half its coefficient (-6.75). Square it (45.5625) and add it to both sides. Add '45.5625' to each side of the equation. -13.5x + 45.5625 + x2 = -2 + 45.5625 Reorder the terms: 45.5625 + -13.5x + x2 = -2 + 45.5625 Combine like terms: -2 + 45.5625 = 43.5625 45.5625 + -13.5x + x2 = 43.5625 Factor a perfect square on the left side: (x + -6.75)(x + -6.75) = 43.5625 Calculate the square root of the right side: 6.600189391 Break this problem into two subproblems by setting (x + -6.75) equal to 6.600189391 and -6.600189391.Subproblem 1
x + -6.75 = 6.600189391 Simplifying x + -6.75 = 6.600189391 Reorder the terms: -6.75 + x = 6.600189391 Solving -6.75 + x = 6.600189391 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.75' to each side of the equation. -6.75 + 6.75 + x = 6.600189391 + 6.75 Combine like terms: -6.75 + 6.75 = 0.00 0.00 + x = 6.600189391 + 6.75 x = 6.600189391 + 6.75 Combine like terms: 6.600189391 + 6.75 = 13.350189391 x = 13.350189391 Simplifying x = 13.350189391Subproblem 2
x + -6.75 = -6.600189391 Simplifying x + -6.75 = -6.600189391 Reorder the terms: -6.75 + x = -6.600189391 Solving -6.75 + x = -6.600189391 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.75' to each side of the equation. -6.75 + 6.75 + x = -6.600189391 + 6.75 Combine like terms: -6.75 + 6.75 = 0.00 0.00 + x = -6.600189391 + 6.75 x = -6.600189391 + 6.75 Combine like terms: -6.600189391 + 6.75 = 0.149810609 x = 0.149810609 Simplifying x = 0.149810609Solution
