Answer :-
Given :-
- Sum of roots = 4
- Product of roots = 1
To Find :-
- Quadratic Polynomial
Solution :-
We know that,
Sum of roots of quadratic polynomial = -b/a
Product of roots = c/a
So,
→ -b/a = 4
→ c/a = 1
Let the value of a be 1
→ -b = 4
→ b = -4
→ c = 1
Hence,
→ a = 1 , b = -4 and c = 1
So, quadratic polynomial = x² - 4x + c
