Answer:

Discriminant: 336

Nature of root: Irrational and Unequal

Step-by-step explanation:

a=10, b=-4, c=-8

b²-4ac

(-4)²-4×10×(-8)

16+320

336

Why Irrational and Unequal?

It is greater than zero but 336 is not a perfect square

Verified answer

Answer:

10x² - 4x - 8 = 0

a=10, b=-4, c=-8

DISCRIMINANT:

b² - 4ac

-4² - 4(10)(-8)

16 + 320

= 336
