Answer 1

:/ what's it mean

Answer 2

I don't think if can be factored

Answer 3

my solution to your problem is general quadratic formula

\[x = \frac{8 \pm \sqrt{(-8)^2 - 4 \times1\times9}}{2\times1}... = \frac{8 \pm \sqrt{28}}{2}\]\\

or

\[x = 4 \pm \sqrt{7}\]

Answer 4

that's ur answer is right???

Answer 5

no if its factorised its

\[(x + 4 + \sqrt{7})(x + 4-\sqrt{7})\]
