Simplifying f(x + -1) = 5x2 + -4x + 7 Reorder the terms: f(-1 + x) = 5x2 + -4x + 7 (-1 * f + x * f) = 5x2 + -4x + 7 (-1f + fx) = 5x2 + -4x + 7 Reorder the terms: -1f + fx = 7 + -4x + 5x2 Solving -1f + fx = 7 + -4x + 5x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -7 + -1f + fx + 4x + -5x2 = 7 + -4x + 5x2 + -7 + 4x + -5x2 Reorder the terms: -7 + -1f + fx + 4x + -5x2 = 7 + -7 + -4x + 4x + 5x2 + -5x2 Combine like terms: 7 + -7 = 0 -7 + -1f + fx + 4x + -5x2 = 0 + -4x + 4x + 5x2 + -5x2 -7 + -1f + fx + 4x + -5x2 = -4x + 4x + 5x2 + -5x2 Combine like terms: -4x + 4x = 0 -7 + -1f + fx + 4x + -5x2 = 0 + 5x2 + -5x2 -7 + -1f + fx + 4x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 -7 + -1f + fx + 4x + -5x2 = 0 The solution to this equation could not be determined.
