If a + b = y, what is a^2 + 2ab + b^2?
a.
y
b.
2y
c.
y^2
d.
2y^2
e.
4y^2

(a+b)^2= a^2+2ab+b^2
(a+b)=y
(a+b)^2=y^2

answer is C

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
