For those who are saying that this video is wrong, indeed is correct. The video displays -2 ± √(7/2)... if you multiply ± √(7/2) with √2 in the numerator and the denominator, you obtain:. ± √(7*2)/√(2^2) which is ± √(14)/2

I get this problem in Stewart's Precalculus and the answer is: -2 ± √14/2

Why?
