<PRE><B>Question 132223</B>
Give exact and approximate solutions to 3 decimal places. 

x^2 - 7x + 5 = 0 
What are the exact solutions? 
x = [7 +-sqrt(7^2 -4*1*5)]/2
x = [7 +-sqrt(69)]/2
x = [7 + sqrt(69)]/2 or x = [7 - sqrt(69)]/2
 
What are the approximate solutions to 3 decimal places.
x = [7 + 6.3066]/2 = 7.6533.. or x = [7 - 6.3066]/2 = 0.3467
