Question

how to find discriminant
​

Answer 1

Answer:

The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it's less than 0, there are no real solutions. If it's equal to 0, there is one real solution.

Answer 2

discriminant is also known as ∆ (delta) in Greek language

u can find out by using formulae:-

b²-4ac

and the answer of roots sign is equal to zero, then it is real and equal

when it is less than zero i.e. -2,-6,-7, etc then it is not real

when it is more than zero i.e. 2,6,7, etc then it is real but unequal
