Simplifying f(x + 6) = x2 + 7x + 7 Reorder the terms: f(6 + x) = x2 + 7x + 7 (6 * f + x * f) = x2 + 7x + 7 (6f + fx) = x2 + 7x + 7 Reorder the terms: 6f + fx = 7 + 7x + x2 Solving 6f + fx = 7 + 7x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -7 + 6f + fx + -7x + -1x2 = 7 + 7x + x2 + -7 + -7x + -1x2 Reorder the terms: -7 + 6f + fx + -7x + -1x2 = 7 + -7 + 7x + -7x + x2 + -1x2 Combine like terms: 7 + -7 = 0 -7 + 6f + fx + -7x + -1x2 = 0 + 7x + -7x + x2 + -1x2 -7 + 6f + fx + -7x + -1x2 = 7x + -7x + x2 + -1x2 Combine like terms: 7x + -7x = 0 -7 + 6f + fx + -7x + -1x2 = 0 + x2 + -1x2 -7 + 6f + fx + -7x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -7 + 6f + fx + -7x + -1x2 = 0 The solution to this equation could not be determined.
