Simplifying 6x2 + 9x + -12 = 143 Reorder the terms: -12 + 9x + 6x2 = 143 Solving -12 + 9x + 6x2 = 143 Solving for variable 'x'. Reorder the terms: -12 + -143 + 9x + 6x2 = 143 + -143 Combine like terms: -12 + -143 = -155 -155 + 9x + 6x2 = 143 + -143 Combine like terms: 143 + -143 = 0 -155 + 9x + 6x2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -25.83333333 + 1.5x + x2 = 0 Move the constant term to the right: Add '25.83333333' to each side of the equation. -25.83333333 + 1.5x + 25.83333333 + x2 = 0 + 25.83333333 Reorder the terms: -25.83333333 + 25.83333333 + 1.5x + x2 = 0 + 25.83333333 Combine like terms: -25.83333333 + 25.83333333 = 0.00000000 0.00000000 + 1.5x + x2 = 0 + 25.83333333 1.5x + x2 = 0 + 25.83333333 Combine like terms: 0 + 25.83333333 = 25.83333333 1.5x + x2 = 25.83333333 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 = 25.83333333 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 25.83333333 + 0.5625 Combine like terms: 25.83333333 + 0.5625 = 26.39583333 0.5625 + 1.5x + x2 = 26.39583333 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 26.39583333 Calculate the square root of the right side: 5.137687547 Break this problem into two subproblems by setting (x + 0.75) equal to 5.137687547 and -5.137687547.Subproblem 1
x + 0.75 = 5.137687547 Simplifying x + 0.75 = 5.137687547 Reorder the terms: 0.75 + x = 5.137687547 Solving 0.75 + x = 5.137687547 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 = 5.137687547 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 5.137687547 + -0.75 x = 5.137687547 + -0.75 Combine like terms: 5.137687547 + -0.75 = 4.387687547 x = 4.387687547 Simplifying x = 4.387687547Subproblem 2
x + 0.75 = -5.137687547 Simplifying x + 0.75 = -5.137687547 Reorder the terms: 0.75 + x = -5.137687547 Solving 0.75 + x = -5.137687547 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 = -5.137687547 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -5.137687547 + -0.75 x = -5.137687547 + -0.75 Combine like terms: -5.137687547 + -0.75 = -5.887687547 x = -5.887687547 Simplifying x = -5.887687547Solution
