Answer 1

Answer:

$\huge \bf {QUESTION}$

Determine the whether the given values of x are zeroes of the given polynomial or not:-

(x+4)(x-5);x=4,x=5

$\huge \bf {SOLUTION}$

Let P(x)=(x+4)(x-5)

Put x= -4

⇒p(-4)=(x+4)(x-5)=(-4+4)(-4-5)=0(-9)=0

Put x=5

⇒p(5)=(x+4)(x-5)=(5+4)(5-5)=9(0)=0

$\bf \therefore The \: given \: value \: of \: x \: is \: a \: zero \\ \bf \: of \: \: the \: given \: polynomial.$
