this question makes no sense. do you mean what are the zeros/roots of this polynomial?

Factoring trinomials are fun!

5x2 - 8x - 4

(5x + 2)(x - 2)

Never forget to check:

5x2 - 10x + 2x - 4

5x2 - 8x - 4

Good everything is in order, now set each parentheses equal to zero to solve for x

5x + 2 = 0

5x = -2

x = - 2/5

x - 2 = 0

x = 2

All done! Now we know the solution set is {-2/5, 2}. Remember smallest number always goes first.
