SOLUTION
CORRECT QUESTION
GIVEN
The zeroes of the quadratic polynomial x² + (m + 1)x + n are 4 and 5
TO DETERMINE
The value of m and n
CONCEPT TO BE IMPLEMENTED
If the Sum of zeroes and Product of the zeroes of a quadratic polynomial is given then the quadratic polynomial is
EVALUATION
Here the given zeroes are 4 and 5
Sum of the zeroes = 4 + 5 = 9
Product of the zeroes = 4 × 5 = 20
So the polynomial with zeroes 4 and 5
Now the given polynomial
On comparison we get
m + 1 = - 9 and n = 20
Consequently we have m = - 10 and n = 20
FINAL ANSWER
The value : m = - 10 and n = 20
