Question

Hw to find whether the roots of a equation is complex or not

Answer 1

find the discrimanent

D=b^2-2ac

if D =0 then two equal roots

D=more than zero then two and distinct roots

D=less than zero then complex roits

Answer 2

For Quadratic Equations ---

By using Discriminate (b²-4ac)

If D(Discriminate) is below 0 then the equation has imaginary roots.

If D>0 then the roots is real
