i got my formula to this point
how from this form i can get it to be with another form
in which we have member
?
q=
in my solution they from the start show this member
but i am not used to work with its formula
i prefer the simple (a+b)^2 form
you said that i should dissasmble every colse on both expressions and regroup
but in the test i idont know the other expression
so how to get this member into my formula
?
