Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to caclulate the discriminant, which is b^2 - 4 a c. ... When discriminant is equal to zero, the roots are equal and real. When discriminant is less than zero, the roots are imaginary.

Answer:
comparing ax2+bx+c=0
a=3,b=5,c=7
Δ=b2 -yac
=9-502-4×3×7
=25-84
=-59
Δ= -59
