Question

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

-2,6

2,-6

-2,-6

2,6​

Answer 1

Answer:

a=0

b= -6

Step-by-step explanation:

x ^2+(a+1)x+b is the quadratic polynomial.

+(a+1)x+b is the quadratic polynomial.2 and −3 are the zeros of the quadratic polynomial.

+(a+1)x+b is the quadratic polynomial.2 and −3 are the zeros of the quadratic polynomial.Thus, 2+(−3)= −(a+1)/1

=> (a+1)/1=1

=1=>a+1=1

=1=>a+1=1=>a=0

=1=>a+1=1=>a=0Also, 2×(−3)=b

=1=>a+1=1=>a=0Also, 2×(−3)=b=>b=−6
