Question

check whether 3and -2 are the zeroes of the polynomial p(x) when p(x)=x2-x-6​

Answer 1

Answer:

Yes , they are the zeroes of respective polynomial

Step-by-step explanation:

1st Method-->

You can check them by putting values (3,-2) into the the polynomial,

if it equals to 0, then they are the zeroes(roots) of the polynomial.

2nd Method-->

One can also Factorize the polynomial-->

(i) By Shree Dharacharya's Formula

(ii) By Middle Term Split method

-->x^2-x-6=0

-->x^2-3x+2x-6=0

-->x(x-3)+2(x-3)=0

-->(x+2)(x-3)=0

--> x= -2, x=3
