find zeros of a polynomial
${x}^{2} - 4$

mic23: the answer is 2

shadowsabers03: And -2.

mic23: no it is right

mic23: 2 is correct

shadowsabers03: And -2 too.

shadowsabers03: x^2 - 4 = 0 is a second degree polynomial, so it has two zeroes, hasn't it?

mic23: got it now

shadowsabers03: Yep.

x^2 - 4 = 0

=> (x - 2)(x + 2) = 0
