Question 41159
You will need to use the quadratic formula.

First simplify the expression:

x^2 -7x+5

Plug it into the Q.F.:

[-(-7) +- sq. root (-7)^2 - 4(1)(5)]/2(1)


 [7 +- sq. root 49 - 20]/2 = 
[7 +- sq. root 29]/2 = 


You will have two solutions
[7 - sq. root 29]/2
and 
[7 + sq. root 29]/2
