Question

$a { }^{2} + 4b {}^{2} - 4ab - 4c {}^{2}$
factorize ​

Answer 1

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

Answer 2

✨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)
