## semaameya Group Title what is the x intercept of y=1+(1/x)+(1/x^2) one year ago one year ago

Is the x intercept when y = 0?

2. semaameya Group Title

Yess!

3. freewilly922 Group Title

Then shouldn't you just try to solve $0=1 + \frac{1}{x}+\frac{1}{x^2}$?

4. semaameya Group Title

I did & i dont think theres a defined answer so i was just checking if i did something wrong

5. freewilly922 Group Title

Ah, did you check the discriminant to see if it was positive/zero/negative?

6. cwrw238 Group Title

multiply each term by x^2

7. cwrw238 Group Title

giving x^2 + x + 1 = 0 and check discriminant as freewill said

8. cwrw238 Group Title

yup

9. semaameya Group Title

alright thanks.
