Simplifying x2 + -3x + -17 = 49 Reorder the terms: -17 + -3x + x2 = 49 Solving -17 + -3x + x2 = 49 Solving for variable 'x'. Reorder the terms: -17 + -49 + -3x + x2 = 49 + -49 Combine like terms: -17 + -49 = -66 -66 + -3x + x2 = 49 + -49 Combine like terms: 49 + -49 = 0 -66 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '66' to each side of the equation. -66 + -3x + 66 + x2 = 0 + 66 Reorder the terms: -66 + 66 + -3x + x2 = 0 + 66 Combine like terms: -66 + 66 = 0 0 + -3x + x2 = 0 + 66 -3x + x2 = 0 + 66 Combine like terms: 0 + 66 = 66 -3x + x2 = 66 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 66 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 66 + 2.25 Combine like terms: 66 + 2.25 = 68.25 2.25 + -3x + x2 = 68.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 68.25 Calculate the square root of the right side: 8.261355821 Break this problem into two subproblems by setting (x + -1.5) equal to 8.261355821 and -8.261355821.Subproblem 1
x + -1.5 = 8.261355821 Simplifying x + -1.5 = 8.261355821 Reorder the terms: -1.5 + x = 8.261355821 Solving -1.5 + x = 8.261355821 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 8.261355821 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 8.261355821 + 1.5 x = 8.261355821 + 1.5 Combine like terms: 8.261355821 + 1.5 = 9.761355821 x = 9.761355821 Simplifying x = 9.761355821Subproblem 2
x + -1.5 = -8.261355821 Simplifying x + -1.5 = -8.261355821 Reorder the terms: -1.5 + x = -8.261355821 Solving -1.5 + x = -8.261355821 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -8.261355821 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -8.261355821 + 1.5 x = -8.261355821 + 1.5 Combine like terms: -8.261355821 + 1.5 = -6.761355821 x = -6.761355821 Simplifying x = -6.761355821Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.761355821, -6.761355821}
