Simplifying f(a + 2) = a2 + -6a + 7 Reorder the terms: f(2 + a) = a2 + -6a + 7 (2 * f + a * f) = a2 + -6a + 7 Reorder the terms: (af + 2f) = a2 + -6a + 7 (af + 2f) = a2 + -6a + 7 Reorder the terms: af + 2f = 7 + -6a + a2 Solving af + 2f = 7 + -6a + a2 Solving for variable 'a'. Reorder the terms: -7 + 6a + af + -1a2 + 2f = 7 + -6a + a2 + -7 + 6a + -1a2 Reorder the terms: -7 + 6a + af + -1a2 + 2f = 7 + -7 + -6a + 6a + a2 + -1a2 Combine like terms: 7 + -7 = 0 -7 + 6a + af + -1a2 + 2f = 0 + -6a + 6a + a2 + -1a2 -7 + 6a + af + -1a2 + 2f = -6a + 6a + a2 + -1a2 Combine like terms: -6a + 6a = 0 -7 + 6a + af + -1a2 + 2f = 0 + a2 + -1a2 -7 + 6a + af + -1a2 + 2f = a2 + -1a2 Combine like terms: a2 + -1a2 = 0 -7 + 6a + af + -1a2 + 2f = 0 The solution to this equation could not be determined.
