Simplifying 5x2 + -35x + -8 = 0 Reorder the terms: -8 + -35x + 5x2 = 0 Solving -8 + -35x + 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'. -1.6 + -7x + x2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + -7x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + -7x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + -7x + x2 = 0 + 1.6 -7x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 -7x + x2 = 1.6 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = 1.6 + 12.25 Reorder the terms: 12.25 + -7x + x2 = 1.6 + 12.25 Combine like terms: 1.6 + 12.25 = 13.85 12.25 + -7x + x2 = 13.85 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 13.85 Calculate the square root of the right side: 3.721558813 Break this problem into two subproblems by setting (x + -3.5) equal to 3.721558813 and -3.721558813.Subproblem 1
x + -3.5 = 3.721558813 Simplifying x + -3.5 = 3.721558813 Reorder the terms: -3.5 + x = 3.721558813 Solving -3.5 + x = 3.721558813 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = 3.721558813 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 3.721558813 + 3.5 x = 3.721558813 + 3.5 Combine like terms: 3.721558813 + 3.5 = 7.221558813 x = 7.221558813 Simplifying x = 7.221558813Subproblem 2
x + -3.5 = -3.721558813 Simplifying x + -3.5 = -3.721558813 Reorder the terms: -3.5 + x = -3.721558813 Solving -3.5 + x = -3.721558813 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = -3.721558813 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -3.721558813 + 3.5 x = -3.721558813 + 3.5 Combine like terms: -3.721558813 + 3.5 = -0.221558813 x = -0.221558813 Simplifying x = -0.221558813Solution
