Question

Which are the zeroes of p(x)=(x-1)(x-2):
A) 1,-2
B)-1,2
C) 1,2
D)-1,-2

Answer 1

The Answer is C ) 1,2 i.e the roots of the given equation are 1 and 2.

1) According to fundamental theorem of Algebra The zeroes a and b of any equation are those which can represent the equation in the form of (x-a)(x-b)=0.

2) Here the equation is given as (x-1)(x-2)=0.
