44

Step-by-step explanation:

The equation is of the form a x ²+bx + c = 0 where

a = 5, b = - 2, c = - 2

The Discriminant is given by:

Δ = b² - 4 * a * c

= (-2²) - (4 * 5 * ( - 2))

= 4 + 40

= 44

Lyric Proctor · Answer 2

The quadratic formula is b squared - 4 (ac)

So we substitute 2 squared - 4 (5•-2)

Which the answer would be 44
