Question

Verify whether 2 and 0 are zeros of the polynomial x square - 2x.​

Answer 1

Answer:

Step-by-step explanation:

To find the zeroes equate the quadratic equation to zero  

x  

2

−2x=0

x(x−2)=0

x=0 and x−2=0  

x=0,2

As zeros means roots of the equation so zeros of this equation are 0,2

Answer 2

Given:

Verify whether 2 and 0 are zeroes of polynomial $\sf{x^2 -2x}$

To Verify:

Whether 2 and 0 are zeroes of polynomial $\sf{x^2 -2x}$

Solution:

Given polynomial is  $\sf{x^2 -2x}$

Let p(x) be the given polynomial

$\sf{x^2 -2x}$

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 that they are zero of the polynomial.
• The given polynomial p(x) is a quadratic polynomial. Hence, a quadratic polynomial has two zeroes.
