Divide all terms by -0.8 the coefficient of the squared term: Divide each side by '-0.8'. 6.75 + 5.25x + x2 = 0 Move the constant term to the right: Add '-6.75' to each side of the equation. 6.75 + 5.25x + -6.75 + x2 = 0 + -6.75 Reorder the terms: 6.75 + -6.75 + 5.25x + x2 = 0 + -6.75 Combine like terms: 6.75 + -6.75 = 0.00 0.00 + 5.25x + x2 = 0 + -6.75 5.25x + x2 = 0 + -6.75 Combine like terms: 0 + -6.75 = -6.75 5.25x + x2 = -6.75 The x term is 5.25x. Take half its coefficient (2.625). Square it (6.890625) and add it to both sides. Add '6.890625' to each side of the equation. 5.25x + 6.890625 + x2 = -6.75 + 6.890625 Reorder the terms: 6.890625 + 5.25x + x2 = -6.75 + 6.890625 Combine like terms: -6.75 + 6.890625 = 0.140625 6.890625 + 5.25x + x2 = 0.140625 Factor a perfect square on the left side: (x + 2.625)(x + 2.625) = 0.140625 Calculate the square root of the right side: 0.375 Break this problem into two subproblems by setting (x + 2.625) equal to 0.375 and -0.375.Subproblem 1
x + 2.625 = 0.375 Simplifying x + 2.625 = 0.375 Reorder the terms: 2.625 + x = 0.375 Solving 2.625 + x = 0.375 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.625' to each side of the equation. 2.625 + -2.625 + x = 0.375 + -2.625 Combine like terms: 2.625 + -2.625 = 0.000 0.000 + x = 0.375 + -2.625 x = 0.375 + -2.625 Combine like terms: 0.375 + -2.625 = -2.25 x = -2.25 Simplifying x = -2.25Subproblem 2
x + 2.625 = -0.375 Simplifying x + 2.625 = -0.375 Reorder the terms: 2.625 + x = -0.375 Solving 2.625 + x = -0.375 Solving for variable 'x'.
