7) Factor 3x² - 12
So, look at those 2 numbers, and see what they both have in common.
They are both divisible by 3! So, basically you divide 3x² and -12 with 3.
3(x² - 4)
It would be factorized like that because if you multiply 3 by x², you would get 3x², and if you multiplied 3 with -4, you would get -4.

Step-by-step explanation:
What you have written here is an equation.
You can define as
a2+b2=y
If you want to derive a^2+b^2 from ( a+b)^2
(a+b)2=a2+b2+2ab
Ora2+b2=(a+b)2−2ab
