Question

It zeroes of polynomial x² + ( a +1) x +b are 2 &- 3,
then find the value of (a+b).
​

Answer 1

Step-by-step explanation:

x

2

+(a+1)x+b is the quadratic polynomial.

2 and −3 are the zeros of the quadratic polynomial.

Thus, 2+(−3)=

1

−(a+1)

=>

1

(a+1)

=1

=>a+1=1

=>a=0

Also, 2×(−3)=b

=>b=−6
