What is the value of the discriminant, b2 − 4ac, for the quadratic equation 0 = −2x2 − 3x + 8, and what does it mean about the number of real solutions the equation has?

73 2 irrational roots

Step-by-step explanation:3^2-(4)(-2)(8)=9=64=73

if the discriminent is a perfect square 2 rational roots

if it is a positive non perfect square 2 irrational roots

if it is 0 1 root

if it is negative no real Root or 2 complex numbers

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

step-by-step explanation:

cuz that one goes over 180
