Question

3 - 12 (a-b)^2
I need an answer plz

Answer 1

Answer:

$3 - 12(a - b) {}^{2}$

Using the identity...

$= > \: (a - b) {}^{2} = a {}^{2} - 2ab \: + \: b {}^{2}$

We can open the bracket :

$3 - 12(a {}^{2} - 2ab \: + b {}^{2} ) \\ 3 - 12a {}^{2} + 24ab \: - 12b {}^{2}$

We can factorize this equation

$3( - 4a {}^{2} + 8ab \: - 4b {}^{2} )$
