Find the discriminant of the following quadratic equations using b^2-4ac and determine the nature of the roots. If the discriminant (d) >0 and also a perfect square the roots are real and rational
If the discriminant (d) > 0 but not a perfect square the roots are real and irrational
If the discriminant (d)=0 the roots are real, rational, equal
if the discriminant (d) < 0 the roots are imaginary.
