Question

Are the roots of the equation x^2-10x+25=0 imaginary?

Answer 1

1. x^2 - 10x + 25 = 0
b^2 - 4ac = (-1)^2 - 4(1)(25) = 100 - 100 = 0

c

Answer 2

The discriminant tells us what type of roots a quadratic has. It has imaginary roots if \[b^2 - 4ac < 0.\]

Answer 3

is it real, rational, irrational, equal,unequal ?

Answer 4

The discriminant is zero so we have repeated real roots.
