factorize (-4-x^2)
You asked:
Factor the expression: \(\displaystyle -4 - {x}^{2}\)
MathBot Answer:
Factorization over the real numbers:
\[- 4 \cdot \left(0.25 x^{2} + 1\right)\]Factorization over the complex numbers:
\[- \left(x - 2 i\right) \left(x + 2 i\right)\]\(i\) is the imaginary unit, defined as \(i^2 = -1\).
