1.Real & Equal
2.Real & Unequal
3.Not real
4.Non-real and equal​

Answer 1

Answer:

i think

real & unequal right answer

Answer 2

Step-by-step explanation: PLEASE MARK ME AS BRAINLIEST

The discriminant of quadratic formula is :- b^2 - 4ac

Putting value of b , a , and c in above formula we get ,

D = (-10)^2 - 4 x 1 x 25

= 100 - 100

= 0

We know that , if D = 0 , then we obtain two equal roots .

It can also be verified by putting the above values in the quadratic formula .

X = (-b +_√D) / 2a
