$a) \\ x^2 + 8x + 16 \\ \\ (x + 4)(x + 4) => (x + 4)^2 \\ \\ \\ b) \\ x^2 - 8x + 16 \\ \\ (x - 4)(x - 4) => (x - 4)^2 \\ \\ \\ c) \\ 4x^2 - 20x + 25 \\ \\ (2x - 5)(2x - 5) => (2x - 5)^2 \\ \\ \\ d) \\ 9x^2 - 12x + 4 \\ \\ (3x - 2)(3x - 2) => (3x - 2)^2 \\ \\ \\ e) \\ x^2 -2x + 1 \\ \\ (x - 1)(x -1) => (x - 1)^2 \\ \\ \\ f) \\ 121x^2 + 22x + 1 \\ \\ (11x + 1)(11x + 1) => (11x + 1)^2$
