Question

The zeroes of p(x) = x² -4 are?​

Answer 1

Here, p(x) = x²-4

Now, if p(x) = 0

0 = x²-4

or, x²-4 =0

or, x² = 4

or, x = ±√4

= ±2

Thus, 2 and -2 are the zeros of p(x).

Answer 2

Answer:

-2 ,+2

Step-by-step explanation:

p(x) = x²-4

we get zeros of p(x) , by equating p(x) to 0

p(x) = 0

x²-4 =0

x² = 4

x = -2 ,+2
