Simplifying 5x2 + -34x + -5 = 0 Reorder the terms: -5 + -34x + 5x2 = 0 Solving -5 + -34x + 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 + -6.8x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -6.8x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -6.8x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -6.8x + x2 = 0 + 1 -6.8x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -6.8x + x2 = 1 The x term is -6.8x. Take half its coefficient (-3.4). Square it (11.56) and add it to both sides. Add '11.56' to each side of the equation. -6.8x + 11.56 + x2 = 1 + 11.56 Reorder the terms: 11.56 + -6.8x + x2 = 1 + 11.56 Combine like terms: 1 + 11.56 = 12.56 11.56 + -6.8x + x2 = 12.56 Factor a perfect square on the left side: (x + -3.4)(x + -3.4) = 12.56 Calculate the square root of the right side: 3.544009029 Break this problem into two subproblems by setting (x + -3.4) equal to 3.544009029 and -3.544009029.Subproblem 1
x + -3.4 = 3.544009029 Simplifying x + -3.4 = 3.544009029 Reorder the terms: -3.4 + x = 3.544009029 Solving -3.4 + x = 3.544009029 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.4' to each side of the equation. -3.4 + 3.4 + x = 3.544009029 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + x = 3.544009029 + 3.4 x = 3.544009029 + 3.4 Combine like terms: 3.544009029 + 3.4 = 6.944009029 x = 6.944009029 Simplifying x = 6.944009029Subproblem 2
x + -3.4 = -3.544009029 Simplifying x + -3.4 = -3.544009029 Reorder the terms: -3.4 + x = -3.544009029 Solving -3.4 + x = -3.544009029 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.4' to each side of the equation. -3.4 + 3.4 + x = -3.544009029 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + x = -3.544009029 + 3.4 x = -3.544009029 + 3.4 Combine like terms: -3.544009029 + 3.4 = -0.144009029 x = -0.144009029 Simplifying x = -0.144009029Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.944009029, -0.144009029}
