Simplifying x2 + -8.5x + 4 = 0 Reorder the terms: 4 + -8.5x + x2 = 0 Solving 4 + -8.5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -8.5x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + -8.5x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -8.5x + x2 = 0 + -4 -8.5x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 -8.5x + x2 = -4 The x term is -8.5x. Take half its coefficient (-4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. -8.5x + 18.0625 + x2 = -4 + 18.0625 Reorder the terms: 18.0625 + -8.5x + x2 = -4 + 18.0625 Combine like terms: -4 + 18.0625 = 14.0625 18.0625 + -8.5x + x2 = 14.0625 Factor a perfect square on the left side: (x + -4.25)(x + -4.25) = 14.0625 Calculate the square root of the right side: 3.75 Break this problem into two subproblems by setting (x + -4.25) equal to 3.75 and -3.75.Subproblem 1
x + -4.25 = 3.75 Simplifying x + -4.25 = 3.75 Reorder the terms: -4.25 + x = 3.75 Solving -4.25 + x = 3.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.25' to each side of the equation. -4.25 + 4.25 + x = 3.75 + 4.25 Combine like terms: -4.25 + 4.25 = 0.00 0.00 + x = 3.75 + 4.25 x = 3.75 + 4.25 Combine like terms: 3.75 + 4.25 = 8 x = 8 Simplifying x = 8Subproblem 2
x + -4.25 = -3.75 Simplifying x + -4.25 = -3.75 Reorder the terms: -4.25 + x = -3.75 Solving -4.25 + x = -3.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.25' to each side of the equation. -4.25 + 4.25 + x = -3.75 + 4.25 Combine like terms: -4.25 + 4.25 = 0.00 0.00 + x = -3.75 + 4.25 x = -3.75 + 4.25 Combine like terms: -3.75 + 4.25 = 0.5 x = 0.5 Simplifying x = 0.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {8, 0.5}
