Simplifying 2x2 + -18x + -40 = 1 Reorder the terms: -40 + -18x + 2x2 = 1 Solving -40 + -18x + 2x2 = 1 Solving for variable 'x'. Reorder the terms: -40 + -1 + -18x + 2x2 = 1 + -1 Combine like terms: -40 + -1 = -41 -41 + -18x + 2x2 = 1 + -1 Combine like terms: 1 + -1 = 0 -41 + -18x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -20.5 + -9x + x2 = 0 Move the constant term to the right: Add '20.5' to each side of the equation. -20.5 + -9x + 20.5 + x2 = 0 + 20.5 Reorder the terms: -20.5 + 20.5 + -9x + x2 = 0 + 20.5 Combine like terms: -20.5 + 20.5 = 0.0 0.0 + -9x + x2 = 0 + 20.5 -9x + x2 = 0 + 20.5 Combine like terms: 0 + 20.5 = 20.5 -9x + x2 = 20.5 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 = 20.5 + 20.25 Reorder the terms: 20.25 + -9x + x2 = 20.5 + 20.25 Combine like terms: 20.5 + 20.25 = 40.75 20.25 + -9x + x2 = 40.75 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 40.75 Calculate the square root of the right side: 6.383572667 Break this problem into two subproblems by setting (x + -4.5) equal to 6.383572667 and -6.383572667.Subproblem 1
x + -4.5 = 6.383572667 Simplifying x + -4.5 = 6.383572667 Reorder the terms: -4.5 + x = 6.383572667 Solving -4.5 + x = 6.383572667 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 = 6.383572667 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 6.383572667 + 4.5 x = 6.383572667 + 4.5 Combine like terms: 6.383572667 + 4.5 = 10.883572667 x = 10.883572667 Simplifying x = 10.883572667Subproblem 2
