Question

find the zeros of the polynomial x2-4

Answer 1

Answer:

2 and -2 are the zeroes of polynomila $x^2-4$

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.

$x^2-4=0$

⇒ $x^2-2^2=0$

As   $a^2-b^2=(a-b)(a+b)$

$x^2-2^2=0$

⇒ $(x-2)(x+2)=0$

⇒ $x=2, x=-2$

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

Answer 2

Step-by-step explanation:

2and-2 are the zeroof polynomual x²-4
