How can you find th discriminate of a function?

Answer 1

Discriminant = b2 - 4ac

A positive answer means two real roots, a 0 answer means one real root and a negative answer means no real roots. Example

X2 + 3X - 10 = 0

a = 1

b = 3

c = -10

32 - 4(1)(- 10)

= 49

----------------a positive answer telling you this quadratic function has two real roots.
