Answer:

x = 2 and x = -1/5

Step-by-step explanation:

Factors into (x-2)(5x+1) = 0 and you have your two values for x.

Or solve by quadratic formula [tex]x = \frac{-(-9) \pm \sqrt{9^{2} - 4(5)(-2)} }{2\cdot5} \\x = \frac{9 \pm 11}{10}.\\[/tex]

Two values, [tex]x = \frac{20}{10} = 2\\x = \frac{-2}{10} = -1/5[/tex]
