Find a quadratic polynomial, the sum of whose zeroes is 4 and one zero...
Quadratic Polynomial with Sum of Zeroes and One Zero Given
To find a quadratic polynomial when the sum of the zeroes and one zero is given, we can use the properties of quadratic equations.

Given Information:
- Sum of zeroes = 4
- One zero = 5

Using the Sum of Zeroes Formula:
The sum of the zeroes of a quadratic polynomial in the form of ax^2 + bx + c is given by the formula:
Sum of zeroes = -b/a

Given Sum of Zeroes:
4 = -b/a

Using the Given Zero:
If one zero is 5, then the product of the zeroes is equal to the constant term divided by the leading coefficient.
Product of zeroes = c/a = 5

Solving for 'a' and 'b':
From the given information, we have:
4 = -b/a and c/a = 5
By substituting c/a = 5 into the product of zeroes formula, we get:
a = c/5
Substitute a = c/5 into the sum of zeroes formula:
4 = -b/(c/5)
4 = -5b/c
20 = -5b
b = -4
Now that we have found the values of 'a' and 'b', we can form the quadratic polynomial:
a = c/5
b = -4
c = 5
Therefore, the quadratic polynomial is:
5x^2 - 20x + 5.
