Question

if the zeros of the quadratic polynomial x square + (a+1)x+b are 2 and minus 3.Find a And b.​

Answer 1

Answer: hey~

a=0,b=−6

Step-by-step explanation:

x² +(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)

=>a+1=1

=>a=0

Also, 2×(−3)=b

=>b=−6
