Simplifying 0.25x2 + -6x + 8 = 0 Reorder the terms: 8 + -6x + 0.25x2 = 0 Solving 8 + -6x + 0.25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.25 the coefficient of the squared term: Divide each side by '0.25'. 32 + -24x + x2 = 0 Move the constant term to the right: Add '-32' to each side of the equation. 32 + -24x + -32 + x2 = 0 + -32 Reorder the terms: 32 + -32 + -24x + x2 = 0 + -32 Combine like terms: 32 + -32 = 0 0 + -24x + x2 = 0 + -32 -24x + x2 = 0 + -32 Combine like terms: 0 + -32 = -32 -24x + x2 = -32 The x term is -24x. Take half its coefficient (-12). Square it (144) and add it to both sides. Add '144' to each side of the equation. -24x + 144 + x2 = -32 + 144 Reorder the terms: 144 + -24x + x2 = -32 + 144 Combine like terms: -32 + 144 = 112 144 + -24x + x2 = 112 Factor a perfect square on the left side: (x + -12)(x + -12) = 112 Calculate the square root of the right side: 10.583005244 Break this problem into two subproblems by setting (x + -12) equal to 10.583005244 and -10.583005244.Subproblem 1
x + -12 = 10.583005244 Simplifying x + -12 = 10.583005244 Reorder the terms: -12 + x = 10.583005244 Solving -12 + x = 10.583005244 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + x = 10.583005244 + 12 Combine like terms: -12 + 12 = 0 0 + x = 10.583005244 + 12 x = 10.583005244 + 12 Combine like terms: 10.583005244 + 12 = 22.583005244 x = 22.583005244 Simplifying x = 22.583005244Subproblem 2
x + -12 = -10.583005244 Simplifying x + -12 = -10.583005244 Reorder the terms: -12 + x = -10.583005244 Solving -12 + x = -10.583005244 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + x = -10.583005244 + 12 Combine like terms: -12 + 12 = 0 0 + x = -10.583005244 + 12 x = -10.583005244 + 12 Combine like terms: -10.583005244 + 12 = 1.416994756 x = 1.416994756 Simplifying x = 1.416994756Solution
