Answer:
Part 1) The exact solutions are
 and
   and   
 
Part 2) (1.79, 8.58)
Step-by-step explanation:
we have
 ----> equation A
 ----> equation A
 ----> equation B
 ----> equation B
we know that
When solving the system of equations by graphing, the solution of the system is the intersection points both graphs
<em>Find the exact solutions of the system</em>
equate equation A and equation B

The formula to solve a quadratic equation of the form 
 
 
is equal to
 
in this problem we have
 
  
so
 
substitute in the formula
 
 
so
