What is the discriminant of the polynomial below 2x^2+5x-8

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
