Question

find the zeroes of x^2-4​

Answer 1

Answer:

Simple! Substitute x for values and you know you would get the answer

Substitute for 2 because you know 2 square is 4 and 4 - 4 = 0

Answer 2

Answer:

2 and -2 are the zeroes of the given polynomial

Step-by-step explanation:

we have to find the zeroes of the polynomial

$x^{2} -4$

To find zeroes we have to put the polynomial equals to 0

$x^{2} -4=0$

⇒$x^{2} -2^{2} =0$    

$a^{2}-b^{2}=(a-b)(a+b)$

So, (x+2)(x-2)=0

Therefore, x =2 ,x= -2

⇒  

Hence, 2 and -2 are the zeroes of the given polynomial.
