Simplifying (-5x * x) + -4x + 17 = 0 Multiply x * x (-5x2) + -4x + 17 = 0 Reorder the terms: 17 + -4x + (-5x2) = 0 Solving 17 + -4x + (-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'. -3.4 + 0.8x + x2 = 0 Move the constant term to the right: Add '3.4' to each side of the equation. -3.4 + 0.8x + 3.4 + x2 = 0 + 3.4 Reorder the terms: -3.4 + 3.4 + 0.8x + x2 = 0 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + 0.8x + x2 = 0 + 3.4 0.8x + x2 = 0 + 3.4 Combine like terms: 0 + 3.4 = 3.4 0.8x + x2 = 3.4 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = 3.4 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 3.4 + 0.16 Combine like terms: 3.4 + 0.16 = 3.56 0.16 + 0.8x + x2 = 3.56 Factor a perfect square on the left side: ((x) + 0.4)((x) + 0.4) = 3.56 Calculate the square root of the right side: 1.886796226 Break this problem into two subproblems by setting ((x) + 0.4) equal to 1.886796226 and -1.886796226.Subproblem 1
(x) + 0.4 = 1.886796226 Simplifying (x) + 0.4 = 1.886796226 x + 0.4 = 1.886796226 Reorder the terms: 0.4 + x = 1.886796226 Solving 0.4 + x = 1.886796226 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = 1.886796226 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 1.886796226 + -0.4 x = 1.886796226 + -0.4 Combine like terms: 1.886796226 + -0.4 = 1.486796226 x = 1.486796226 Simplifying x = 1.486796226Subproblem 2
(x) + 0.4 = -1.886796226 Simplifying (x) + 0.4 = -1.886796226 x + 0.4 = -1.886796226 Reorder the terms: 0.4 + x = -1.886796226 Solving 0.4 + x = -1.886796226 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = -1.886796226 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -1.886796226 + -0.4 x = -1.886796226 + -0.4 Combine like terms: -1.886796226 + -0.4 = -2.286796226 x = -2.286796226 Simplifying x = -2.286796226Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.486796226, -2.286796226}
