Consider the quadratic equation. x^2=4x-5. How many solutions does the equation have? a.) one real solution b.) two real solutions c.)no real solutions d.)cannot be determined

Respuesta :

C - you have to check the discriminant (the number under the radical in the quadratic formula). If it’s positive, there are two real solutions. If it’s zero, just one. And if it’s negative, there are no real solutions.
I am pretty sure it is b.)two real solutions
