Answer:yes

Step-by-step explanation:

Given

[tex]ax^2+bx+c=0[/tex]

a,b,c<0

For quadratic equation to have real roots Discriminant should be greater than zero

D>0

[tex]\sqrt{b^2-4ac}>0[/tex]

Thus

[tex]b^2-4ac>0[/tex]

b is negative so its square is positive

a & c is negative so their product is positive

so Discriminant is Positive when

[tex]b^2>4ac[/tex]
