So im in a Math exam and there is a question i do not know how to answer.
So the question is 'N sqaured - N - 90 = 0' solve the eqaution.
so please help me, i do not have a clue how to answer it and i cannot fail again.
+130465 N^2 - N - 90 = 0 factor
(N - 10) (N + 9) = 0 setting each factor to 0, we have that N = 10 or N = -9
Is this for real ?
Is a person sitting in an exam really being sent the answer to a question ?
Hopefully the exam was already over when the answer was posted.
+118696 I share your concern.
It looks like that answer was not given until an hour after the question was posted so it most likely did not help in the actual exam.
This is why internet access should NEVER be allowed in exams!
(unless the ability to use the internet is being tested)
