Question

the zeros of polynomial x2- 2x- 3are:- ​

Answer 1

Answer:

-1 and 3 are the zeroes of the polynomial.

Step-by-step explanation:

Let p(x) = x²-2x-3

-> x²-2x-3=0

By Splitting the middle term,

x²-(3-1)x-3=0

-> x²-3x+1x-3=0

->. x(x-3)+1(x-3)

->. (x+1)(x-3)

Therefore,

x+1=0. ; x-3=0

-> x=-1 ; x=3

Hence, -1 and 3 are the zeroes of the polynomial.
