Answer:

hello please mark as brainleist

Answer 2

Comparing the given quadratic equationn with ax² + bx + c =0 , we get

a=1, b=-1 and c=-1

Using discriminant formula

D=b²-4ac

=(-1)²-4(1)(-1)

=1+4

=5

Here, D>0

Therefore, we say that the quadratic equation has two disnict real roots in this case.
