Answer 2

We know that a discriminant is an index to indicate whether the quadratic function has no intersection (D<0), intersect as single point (D=0) or intersect at multiple roots (D>0) with the horizontal axis. Discriminant of a quadratic equation ax

2 +bx+c=0 is D=b*2 −4ac.

In the given quadratic equation x*2

+5x+5=0, a=1,b=5 and c=5, therefore, the discriminant is:

D=b*2 −4ac=(5)*2 −(4×1×5)=25−20=5

5.
