Answer:
D.0
Step-by-step explanation:
Our system of equations is
then we can conclude that
- x²+1 = x
- x²+1-x = 0
- x²-x+1 = 0
This is a quadratic equation so we will use the dicriminant method:
Let Δ be our dicriminant
- a= 1
- b= -1
- c= 1
- Δ = (-1)²-4*1*1 = 1-4 = -3 < 0
The dicriminant is negative so this equation has no real solutions
the the system has no real solutions
