Step-by-step explanation:
a²+4b²-4ab-4c²
using the formula a² -2ab+b²=(a-b)²
(a-2b)² -(2c)²
now using a² -b²=(a+b)(a-b)
you get,
(a-2b-2c)(a-2b+2c)
this is your answer

✨THERE IT GOES
________________
a^2 + 4b^2 - 4ab - 4c^2
= a^2 - 2 * 2b * a + (2b)^2 - (2c)^2
= (a - 2b)^2 - (2c)^2
= (a - 2b + 2c)(a - 2b - 2c)
