i need help an the question is x=2+1/x
If this is the equation x = 2 + (1/x) then first multiply through by x to get:
x2 = 2x + 1
Rearrange:
x2 - 2x - 1 = 0
Solve using the quadratic formula:
x2−2×x−1=0⇒{x=1−√2x=√2+1}⇒{x=−0.414213562373095x=2.414213562373095}
This doesn't make sense. How can x = something that has x.
If x = 1: 1 = (2+1)/1 ? NO & 1 = 2 + (1/1) ? NO.
Also, parentheses are very important! Is it (2+1)/x or 2+(1/x)?
