Question

Without determining the roots,comment on nature of roots of following equations
25x^2+20x+4=0
plz sum solve full​

Answer 1

Answer:

a=25, b=20 and c=4

D=b^2-4ac

D=20^2-4x25x4

D=400-400

D=0

So two roots are equal

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

The given equation is 25x²+20x+4=0

As compared to ax²+bx+c=0

a=25,b=20 and c=4.

Now discriminant = b²-4ac=20²-4×25×4

=400-400=0

So the roots are real and equal.
