Question

Do I have the correct answer? Or did I solve it incorrectly?

Answer 1

we have the equation

`9x^2-30x+25=0`

we have

a=9

b=-30

c=25

The discriminant is equal to

`D=b^2-4ac`

substitute the given values

`D=(-30)^2-4(9)(25)`

D=0

that means

the equation has two real, identical roots
