Subtract the following polynomials: (x^2-4)-(x^2+4) 1 -8 0 8

To subtract the polynomials \( \left(x^{2}-4\right)-\left(x^{2}+4\right) \), follow these steps:<br /><br />1. Distribute the negative sign across the second polynomial:<br /> \[<br /> x^2 - 4 - (x^2 + 4) = x^2 - 4 - x^2 - 4<br /> \]<br /><br />2. Combine like terms:<br /> \[<br /> (x^2 - x^2) + (-4 - 4) = 0 - 8 = -8<br /> \]<br /><br />Therefore, the result of the subtraction is \(-8\).
