Thank you for all the responses!
It turned out that my "theory" contained an error - the answer is 0.2544, and
this was confirmed with the simulation in R.
My students will be impressed - and I will quote where I found the great help.

Greetings,
Let me present my modest proposition as function with an input and an
output, it is based on the valuable solution of Alberto Monteiro. I have
choosen delta superior or equal to 0 wich still provide a REAL solution :
prob <- function(n){
a <- runif(n)
b <- runif(n)
c <- runif(n)
delta

Hallo
I would appreciate any help with the following.
Problem: Suppose A, B and C are independent U(0,1) random variables. What is
the probability that A(x^2) + Bx + C has real roots?
I have done the theoretical work and obtained an answer of 1/9 = 0..
Now I want to show my students to get
