Question

Q3. If the zeroes of the quadratic polynomial r+ (a+ 1)x +b are 2 and -3, then

(a) a =-7, b=-1

(c) a = 2, b=-6

(b) a -5, b=-1

(d) a-0, b=-6​

Answer 1

Heyaa!! Here is the answer

(d) a= 0 , b=-6

Step-by-step explanation:

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
