Answer:

89 2 irrational roots

Step-by-step explanation:

The discriminant Is b²-4ac when the equation is in the form

ax²+bx+c so in the equation

a=2 b=5 and c=-8

plug into the equation for the discriminant

so 5²-4(2)(-8)

25-(-64) 2 negatives make a positive so

25+64=89

since 89 isn’t a perfect square 2 irrational roots
