Step-by-step explanation:

5x² -6x -4 = 0

By comparing with ax² +bx + c = 0, we get

a = 5

b = -6

c = -4

discriminant

= b²-4ac

=( -6)²-4(5)(-4)

= 36 +80

= 116

b²-4ac > 0

∴ Nature of roots is real.

Roots are (6+√116)/10 and (6-√116)/10.

{By using quadratic equation formula,

[-b±√(b²-4ac)]/2a.}
