Ok so now I am really confused. This is a review problem for algebra: xsquare -4x+1=0. I need to solve for x. I dont think I factor because this problem is prime, maybe complete the square:
xsquare-4x=-1
xsquare-4x+4=3
then i get confused..
x[sup:s7n53ozh]2[/sup:s7n53ozh]-4x=-1
x[sup:s7n53ozh]2[/sup:s7n53ozh]-4x+4=3
then i get confused..
Now factor the left side and write as a binomial squared. Then you are in position to take the square root of both sides and go from there. When you take the square root of both sides don't forget that the right side will be preceded by a "plus or minus" sign.
