Question

what is the number of real solutions -11x2=x+11

Answer 1

it is a second-degree equation, the number of solutions is 2, you have to do more to find out if any of them are real.

11x^2+x+11=0

x=(-1+- sqrt(1-4*11*11)/22

so, the radical is a squart of a large negative number, so there are no real solutions.

Answer 2

Thank you bob, these types of problems confuse me soooo much.

I'm glad you explained it instead of just giving the answer
