Answer:

(a - 6)²

(3c + 1)²

30e(e - 1)²

Step-by-step explanation:

a^2-12a+36

a² - 6a - 6a + 36

a(a - 6) - 6(a - 6)

(a - 6)(a - 6)

(a - 6)²

9c^2 + 6c + 1

9c² + 3c + 3c + 1

3c(3c + 1) + 1(3c + 1)

(3c + 1)(3c + 1)

(3c + 1)²

30e^3 - 60e^2 + 30e

30e(e² - 2e + 1)

30e(e² - e - e + 1)

30e[e(e - 1) - (e - 1)]

30e(e - 1)(e - 1)

30e(e - 1)²
