Answer 2

Hello from MrBillDoesMath!

Answer:

0

Discussion:

For the quadratic ax^2 + b^x + c, the discriminant is b^2 - 4ac. In our case, the discriminant is

(-20)^2 - 4 (4)(25) =

400 - 4 (100) =

0

(This means the polynomial has a duplicate root. In fact it factors as (2x-5)^2 ).

Thank you,
