Question

If the discriminant of a quadratic equation is 10, how many solutions does the equation have?
A. 0
B. 1
C. 2
D. no real solutions

Answer 1

Answer:

C. 2

Step-by-step explanation:

If the discriminant is >0 we have 2 real solutions

If the discriminant is =0 we have 1 real solutions

If the discriminant is <0 we have 2 complex solutions (no real solutions)

since 10>0 we have 2 real solutions
