Let u and v be the solutions to 3x^2 + 5x + 7 = 2x^2 - 4x - 11. Find u/v + v/u.

Students, please don't believe guests who post only an "answer"

without showing you the way they obtained their so-called answer.

Their "answers" are wrong so often, I think they're doing it on purpose.

I believe that they're trolls, trying to get you in trouble with your teacher.

*Let u and v be the solutions to 3x^2 + 5x + 7 = 2x^2 - 4x - 11. Find u/v + v/u.*

3x^{2} + 5x + 7 = 2x^{2} – 4x – 11

x^{2} + 9x + 18 = 0

(x + 6)(x + 3) = 0 therefore u and v equal **–6** and **–3** (not necessarily in that order)

–6 / –3 = 2

–3 / –6 = 0**.**5 so their total is **2.5**
