SOLUTION
GIVEN
The zeros of the quadratic polynomial
x² + (a + 1)x + b are 2 and - 3
TO DETERMINE
The value of a and b
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 - 2 & 3
So the polynomial is
Now the given polynomial is x² + (a + 1)x + b
Comparing we get
a + 1 = 1 and b = - 6
⇒ a = 0 and b = - 6
FINAL ANSWER
a = 0 and b = - 6
