Question 1658
Very simple. I will show you:
y >/= x^2-3x+1     G
0=x^2-3x+1         lety=0,let sign be=
{{{x=(-b+-sqrt(b^2-4*a*c))/(2*a)}}}  QF
{{{x=(3+-sqrt(5))/(2)}}}       Sub,S
And this is your answer. It is in the radical form. There is no sqrt of five besides 2.24. And besides, this is the scantron answer. Good Luck in all of your other problems!
