    Again, no. Do you recognize that this is a difference in squares?

    Ok. Do you see how s^2 * s^2 = s^4? and that 4 * 4 = 16?

    Nope... \[s^{4} - 16 = (s^{2} - 4)(s^{2} + 4)\]Now, do you realize that s^2 - 4 is also a difference in squares?

    Alright. The form \[a^{2} - b^{2} = (a + b)(a - b)\]Therefore, \[s^{2} - 4 = (s + 2)(s - 2) The same for s^2 + 4. It turns imaginary. \[s^{2} + 4 = (s - 2i)(s + 2i)
