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

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
