Answer:
1
Step-by-step explanation:
I'm not sure if this is right, but I think it's 1. If you think about the simplest quintic polynomial, x^5, and set it to any real number, you'll always get 1 solution. I don't think it's possible to have 0 or no real solutions. Hope this helps!
Answer:
dy/dx = 0
Step-by-step explanation:
In y + y^2 = 10
Differentiating In y = 1/ydy/dx
Differentiating y^2 = 2ydy/dx
Differentiating a constant (10) = 0
1/ydy/dx + 2ydy/dx = 0
dy/dx(1/y + 2y) = 0
dy/dx = 0/(1/y + 2y) = 0
