Answer:

[tex]x = -\frac45, x = 0[/tex]

Step-by-step explanation:

Hello!

To solve this, we have to simplify the radical and fraction.

Simplify:

  • [tex]x = \frac{-4 \pm\sqrt{4^2 - 4(5)(0)}}{2(5)}[/tex]
  • [tex]x = \frac{-4 \pm \sqrt{16}}{10}[/tex]
  • [tex]x = \frac{-4 \pm 4}{10}[/tex]
  • [tex]x = -\frac45, x = 0[/tex]

There are two solutions for x: -0.8, and 0.
