What is the value of the discriminant for the quadratic equation 0 = 2x2 + x – 3?
discriminant = b2 – 4ac
–25
–23
25
26

the awnser would be 25

Step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the radius is 2 times the diameter.
