Step-by-step explanation:
We are given ,
and
are zeros of the function. We can use the sum and product of roots. You may have come across these equations before ↓
Since the coefficients are already in a, b, and c's, we do not need to sub in anything else.
Now, you are asked to evaluate . The next step after finding the roots above ↑, is to factorise this equation to be solved.
=
Sub in each respective roots,
=
=
