Simplifying f2 + 3f + -47 = 0 Reorder the terms: -47 + 3f + f2 = 0 Solving -47 + 3f + f2 = 0 Solving for variable 'f'. Begin completing the square. Move the constant term to the right: Add '47' to each side of the equation. -47 + 3f + 47 + f2 = 0 + 47 Reorder the terms: -47 + 47 + 3f + f2 = 0 + 47 Combine like terms: -47 + 47 = 0 0 + 3f + f2 = 0 + 47 3f + f2 = 0 + 47 Combine like terms: 0 + 47 = 47 3f + f2 = 47 The f term is 3f. 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. 3f + 2.25 + f2 = 47 + 2.25 Reorder the terms: 2.25 + 3f + f2 = 47 + 2.25 Combine like terms: 47 + 2.25 = 49.25 2.25 + 3f + f2 = 49.25 Factor a perfect square on the left side: (f + 1.5)(f + 1.5) = 49.25 Calculate the square root of the right side: 7.017834424 Break this problem into two subproblems by setting (f + 1.5) equal to 7.017834424 and -7.017834424.Subproblem 1
f + 1.5 = 7.017834424 Simplifying f + 1.5 = 7.017834424 Reorder the terms: 1.5 + f = 7.017834424 Solving 1.5 + f = 7.017834424 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + f = 7.017834424 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + f = 7.017834424 + -1.5 f = 7.017834424 + -1.5 Combine like terms: 7.017834424 + -1.5 = 5.517834424 f = 5.517834424 Simplifying f = 5.517834424Subproblem 2
f + 1.5 = -7.017834424 Simplifying f + 1.5 = -7.017834424 Reorder the terms: 1.5 + f = -7.017834424 Solving 1.5 + f = -7.017834424 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + f = -7.017834424 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + f = -7.017834424 + -1.5 f = -7.017834424 + -1.5 Combine like terms: -7.017834424 + -1.5 = -8.517834424 f = -8.517834424 Simplifying f = -8.517834424Solution
The solution to the problem is based on the solutions from the subproblems. f = {5.517834424, -8.517834424}
