Q:
# What is the value of the discriminant of the quadratic equation β2x2 = β8x + 8, and what does its value mean about the number of real number solutions the equation has?The discriminant is equal to 0, which means the equation has no real number solutions.The discriminant is equal to 0, which means the equation has one real number solution.The discriminant is equal to 128, which means the equation has no real number solutions.The discriminant is equal to 128, which means the equation has two real number solutions.

Accepted Solution

A:

the discriminant is bΒ²-4ac

-2xΒ²+8x-8=0

in this case, b=8, a=-2, c=-8

so bΒ²-4ac=8Β²-4(-2)(-8)=0

choice B is correct.Β

-2xΒ²+8x-8=0

in this case, b=8, a=-2, c=-8

so bΒ²-4ac=8Β²-4(-2)(-8)=0

choice B is correct.Β
