c.)5+sqrt33/4
d.)5+sqrt33/2
I am not even close to any of these options. please help This question is from textbook algebra

none of the answers seem to be correct

x^2=5x+2 ... x^2-5x=2 ... x^2-5x+(-5/2)^2=2+(-5/2)^2 ... (x-(5/2))^2=33/4 ... x-(5/2)=+-sqrt(33/4) ... x=(5/2)+-sqrt(33/4)

answer d would work with some added parentheses ... (5/2)+-sqrt(33/4)=(5+-sqrt33)/2
