Simplifying x2 + -9x + 2 + -0.25 = 0.25 Reorder the terms: 2 + -0.25 + -9x + x2 = 0.25 Combine like terms: 2 + -0.25 = 1.75 1.75 + -9x + x2 = 0.25 Solving 1.75 + -9x + x2 = 0.25 Solving for variable 'x'. Reorder the terms: 1.75 + -0.25 + -9x + x2 = 0.25 + -0.25 Combine like terms: 1.75 + -0.25 = 1.5 1.5 + -9x + x2 = 0.25 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 1.5 + -9x + x2 = 0.00 Begin completing the square. Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + -9x + -1.5 + x2 = 0.00 + -1.5 Reorder the terms: 1.5 + -1.5 + -9x + x2 = 0.00 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + -9x + x2 = 0.00 + -1.5 -9x + x2 = 0.00 + -1.5 Combine like terms: 0.00 + -1.5 = -1.5 -9x + x2 = -1.5 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = -1.5 + 20.25 Reorder the terms: 20.25 + -9x + x2 = -1.5 + 20.25 Combine like terms: -1.5 + 20.25 = 18.75 20.25 + -9x + x2 = 18.75 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 18.75 Calculate the square root of the right side: 4.330127019 Break this problem into two subproblems by setting (x + -4.5) equal to 4.330127019 and -4.330127019.Subproblem 1
x + -4.5 = 4.330127019 Simplifying x + -4.5 = 4.330127019 Reorder the terms: -4.5 + x = 4.330127019 Solving -4.5 + x = 4.330127019 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 4.330127019 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 4.330127019 + 4.5 x = 4.330127019 + 4.5 Combine like terms: 4.330127019 + 4.5 = 8.830127019 x = 8.830127019 Simplifying x = 8.830127019Subproblem 2
x + -4.5 = -4.330127019 Simplifying x + -4.5 = -4.330127019 Reorder the terms: -4.5 + x = -4.330127019 Solving -4.5 + x = -4.330127019 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = -4.330127019 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -4.330127019 + 4.5 x = -4.330127019 + 4.5 Combine like terms: -4.330127019 + 4.5 = 0.169872981 x = 0.169872981 Simplifying x = 0.169872981Solution
