Question

Why can’t you Factor x^2+9

Answer 1

You can't answer this because there isn't a regular x value, there is only a x squared

Explanation:

Answer 2

`~~~~~~x^2 +9 = 0\\\\\implies x^2 = -9\\\\\implies x = \pm√(-9)\\\\\implies x=\pm 3i\\\\\text{Which is not real, so the given expression can't be factored for} ~x \in \mathbb{R}.`
