Simplifying x2 + 39x + 47 = 0 Reorder the terms: 47 + 39x + x2 = 0 Solving 47 + 39x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-47' to each side of the equation. 47 + 39x + -47 + x2 = 0 + -47 Reorder the terms: 47 + -47 + 39x + x2 = 0 + -47 Combine like terms: 47 + -47 = 0 0 + 39x + x2 = 0 + -47 39x + x2 = 0 + -47 Combine like terms: 0 + -47 = -47 39x + x2 = -47 The x term is 39x. Take half its coefficient (19.5). Square it (380.25) and add it to both sides. Add '380.25' to each side of the equation. 39x + 380.25 + x2 = -47 + 380.25 Reorder the terms: 380.25 + 39x + x2 = -47 + 380.25 Combine like terms: -47 + 380.25 = 333.25 380.25 + 39x + x2 = 333.25 Factor a perfect square on the left side: (x + 19.5)(x + 19.5) = 333.25 Calculate the square root of the right side: 18.255136264 Break this problem into two subproblems by setting (x + 19.5) equal to 18.255136264 and -18.255136264.Subproblem 1
x + 19.5 = 18.255136264 Simplifying x + 19.5 = 18.255136264 Reorder the terms: 19.5 + x = 18.255136264 Solving 19.5 + x = 18.255136264 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-19.5' to each side of the equation. 19.5 + -19.5 + x = 18.255136264 + -19.5 Combine like terms: 19.5 + -19.5 = 0.0 0.0 + x = 18.255136264 + -19.5 x = 18.255136264 + -19.5 Combine like terms: 18.255136264 + -19.5 = -1.244863736 x = -1.244863736 Simplifying x = -1.244863736Subproblem 2
x + 19.5 = -18.255136264 Simplifying x + 19.5 = -18.255136264 Reorder the terms: 19.5 + x = -18.255136264 Solving 19.5 + x = -18.255136264 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-19.5' to each side of the equation. 19.5 + -19.5 + x = -18.255136264 + -19.5 Combine like terms: 19.5 + -19.5 = 0.0 0.0 + x = -18.255136264 + -19.5 x = -18.255136264 + -19.5 Combine like terms: -18.255136264 + -19.5 = -37.755136264 x = -37.755136264 Simplifying x = -37.755136264Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.244863736, -37.755136264}
