Simplifying 5x2 + -25x + 13 = 0 Reorder the terms: 13 + -25x + 5x2 = 0 Solving 13 + -25x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 2.6 + -5x + x2 = 0 Move the constant term to the right: Add '-2.6' to each side of the equation. 2.6 + -5x + -2.6 + x2 = 0 + -2.6 Reorder the terms: 2.6 + -2.6 + -5x + x2 = 0 + -2.6 Combine like terms: 2.6 + -2.6 = 0.0 0.0 + -5x + x2 = 0 + -2.6 -5x + x2 = 0 + -2.6 Combine like terms: 0 + -2.6 = -2.6 -5x + x2 = -2.6 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -2.6 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -2.6 + 6.25 Combine like terms: -2.6 + 6.25 = 3.65 6.25 + -5x + x2 = 3.65 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 3.65 Calculate the square root of the right side: 1.910497317 Break this problem into two subproblems by setting (x + -2.5) equal to 1.910497317 and -1.910497317.Subproblem 1
x + -2.5 = 1.910497317 Simplifying x + -2.5 = 1.910497317 Reorder the terms: -2.5 + x = 1.910497317 Solving -2.5 + x = 1.910497317 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 1.910497317 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 1.910497317 + 2.5 x = 1.910497317 + 2.5 Combine like terms: 1.910497317 + 2.5 = 4.410497317 x = 4.410497317 Simplifying x = 4.410497317Subproblem 2
x + -2.5 = -1.910497317 Simplifying x + -2.5 = -1.910497317 Reorder the terms: -2.5 + x = -1.910497317 Solving -2.5 + x = -1.910497317 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -1.910497317 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -1.910497317 + 2.5 x = -1.910497317 + 2.5 Combine like terms: -1.910497317 + 2.5 = 0.589502683 x = 0.589502683 Simplifying x = 0.589502683Solution
