Question

Verify whether 2 and 0 are zeroes of the polynomial X - 2x.​

Answer 1

Answer:

here is the answer

Step-by-step explanation:

p(x)=x-2x

p(2)=2-2(2)=2-4=-2

p(0)=0-2(0)=0

Answer 2

Given :

Verify whether 2 and 0 are zeroes of polynomial $x^2 -2x$

To Verify :

Whether 2 and 0 are zeroes of polynomial $x^2 -2x$

Solution :

Given polynomial is  $x^2 -2x$

Let p(x) be the given polynomial

 $p(x)= x^2 -2x$

• To verify that 2 and 0 are zeroes of polynomial
• p(x) we have to put x=2 and x=0 in p(x) and hence it must satisfies the polynomial.

$\: \: \: \: \: \: \: \fbox{ p(x)=0 for x=2 and 0} \orange\bigstar$

Now put x=2 in p(x)

$\sf{p(2)=2^2-2(2)} \\ \: \: \sf{=4 - 4} \\ \: \: \: \: \: \: \: \: \: \: \: \boxed {\frak{p(2) =0}} \pink\bigstar$

Now put x=0 in p(x)

$\sf{p(0)=0^2-2(0)} \\ \: \: \sf{=0-0} \\ \: \: \: \: \: \: \: \: \: \: \: \boxed {\frak{p(0) =0}} \blue\bigstar$

• Hence, 0 and 2 both satisfy
• The given polynomial p(x) is a quadratic polynomial. Hence, a quadratic polynomial has two zeroes.
