Question

check wether 4and -4 are zeros of polynomial x-4​

Answer 1

Answer:

p(x)= x-4

p+4)= 4-4

=0

therefore, yes 4 is a zero of polynomial x-4

Now, again

p(-4)= x-4

= -4-4

=-8

Therefore, -4 is not a zero of polynomial x-4

Answer 2

$\huge\underline\mathrm{Question-}$

check whether 4 and -4 are zeroes of polynomial (x-4) or not.

$\huge\underline\mathrm{Solution-}$

1) Let's check either 4 is the zero of given polynomial or not.

★ put x = 4

=> 4 - 4

=> 0

$\therefore$ 4 is the zero of given polynomial.

$\rule{200}2$

2) Let's check either -4 is the zero of given Polynomial or not.

★ Put x = -4

=> - 4 - 4

=> -8

$\therefore$ -4 is not the zero of given Polynomial.
