Question

if a polynomial is a perfect square then its factor will be repeated _number of times. a) odd. b) zero. c) even. d) none of the above​

Answer 1

ANSWER

option (a) odd number of times

EXPLANATION

consider an example

1.take monomial (x-2) ^2

the factors of this monomial is (x-2)

since degree of monomial is 2 (even) but factor is 1(odd)

2.take binomial

(x-y) ^2

since degree of binomial is 2

but factors is only one

it doesn't have pair factors because it is perfect square .
