Simplifying 80 = (2x + -5) * x Reorder the terms: 80 = (-5 + 2x) * x Reorder the terms for easier multiplication: 80 = x(-5 + 2x) 80 = (-5 * x + 2x * x) 80 = (-5x + 2x2) Solving 80 = -5x + 2x2 Solving for variable 'x'. Reorder the terms: 80 + 5x + -2x2 = -5x + 5x + 2x2 + -2x2 Combine like terms: -5x + 5x = 0 80 + 5x + -2x2 = 0 + 2x2 + -2x2 80 + 5x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 80 + 5x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -40 + -2.5x + x2 = 0 Move the constant term to the right: Add '40' to each side of the equation. -40 + -2.5x + 40 + x2 = 0 + 40 Reorder the terms: -40 + 40 + -2.5x + x2 = 0 + 40 Combine like terms: -40 + 40 = 0 0 + -2.5x + x2 = 0 + 40 -2.5x + x2 = 0 + 40 Combine like terms: 0 + 40 = 40 -2.5x + x2 = 40 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = 40 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 40 + 1.5625 Combine like terms: 40 + 1.5625 = 41.5625 1.5625 + -2.5x + x2 = 41.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 41.5625 Calculate the square root of the right side: 6.446898479 Break this problem into two subproblems by setting (x + -1.25) equal to 6.446898479 and -6.446898479.Subproblem 1
x + -1.25 = 6.446898479 Simplifying x + -1.25 = 6.446898479 Reorder the terms: -1.25 + x = 6.446898479 Solving -1.25 + x = 6.446898479 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = 6.446898479 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 6.446898479 + 1.25 x = 6.446898479 + 1.25 Combine like terms: 6.446898479 + 1.25 = 7.696898479 x = 7.696898479 Simplifying x = 7.696898479Subproblem 2
x + -1.25 = -6.446898479 Simplifying x + -1.25 = -6.446898479 Reorder the terms: -1.25 + x = -6.446898479 Solving -1.25 + x = -6.446898479 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = -6.446898479 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -6.446898479 + 1.25 x = -6.446898479 + 1.25 Combine like terms: -6.446898479 + 1.25 = -5.196898479 x = -5.196898479 Simplifying x = -5.196898479Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.696898479, -5.196898479}
