Question

check weather -2 and 2 are the zeros of polynomial x²-5x+6​

Answer 1

Answer:

(a) -2 is not the zero of polynomial

(b) 2 is the zero of polynomial

Step-by-step explanation:

$p(x)=$ $x^{2}-5x+6$

$p(-2)=(-2)^{2}-5(-2)+6 \\= 4+10+6\\= 20$

$p(2)=2^{2}-5(2)+6\\ = 4-10+6\\=0$

Answer 2

Given:-

๛Zeros:-

•-2–[p(-2)=p(x)]

•2–[p(2)=p(x)]

๛p(x)=x²-5x+6

$\rule{200}{1}$

To Find:-

✪If they are th zeros of the Polynomial?

AnsWer:-

☞p(-2) is not one of the zeros.

☞p(2) is one of the Zeros.

$\rule{200}{1}$

➜p(-2)=(-2)²-5×(-2)+6

↝p(-2)=4+10+6

↝p(-2)=14+6

↝p(-2)=20

$\rule{200}{1}$

➜p(2)=(2)²-5×2+6

↝p(2)=4-10+6

↝p(-2)=-6+6

↝p(2)=0

$\rule{200}{2}$
