how did you found the value of a and b
I did not understood anything
i had the value of a - b and ab and then i found the value of a + b. since a^2 - b^2 = (a- b)(a+b)
and i have both a - b and a + b, then it is done
from where did you took the value of a and b
i did not take the value of a and b. i do not need them. i just need a - b and a + b
why did you took 4ab
because i get -2ab from (a- b)^2 so i need 4ab to get then 2ab.
It is a correct answer .thx
