Question

P (x) =(x-1) (x-2) (x-3) find the zero of the polynomial in each of the following ​

Answer 1

Answer:

Finding zero of p(x)=(x−1)(x−2)(x−3), is same as solving the equation  p(x)=0.

⇒(x−1)(x−2)(x−3)=0

⇒(x−1)=0,(x−2)=0,(x−3)=0

⇒x=1,2,3.

Therefore, options A, B and C are correct

Finding zero of p(x)=(x−1)(x−2)(x−3),

is same as solving the equation

✦ p(x)=0.

⇒(x−1)(x−2)(x−3)=0

⇒(x−1)=0,(x−2)=0,(x−3)=0

⇒x=1,2,3.
