Use the quadratic formula to find the roots x^2-4x+1=0 A. Express the roots in the simplest radical form. B. Express the roots to the nearest hundredth

* x^2 ---> x to the second power *

Divide all this by 2a. the solutions for x are the answer to the question. There will be two answers as for the first one, plus the second bit of the top line, and for the second solution, minus it (hence the "plus or minus" bit). The "a" is the value of x^2, "b" is the value of the x and c is the value of the number. You should get the answers as being x=3.73 and x=0.27 ok? Ask me if you want more info/help

Date: 4/2/2002 8:23:00 AM  From Authorid: 35042    Well the answers to C will be 373 hundreths and 27 hundreths. As for the radical form, I can't remember how to do it... Sorry!! lol
