What is the discriminant of 9x^2+2=10x^2

Mathematics
1 answer:
Tcecarenko [31]2 years ago
3 0

Answer:

8

Step-by-step explanation:

To find the discriminant, we need to get the equation in standard form

9x^2+2=10x^2

Subtract  10x^2 from each side

9x^2-10x^2+2=10x^2-10x^2

-x^2 +2 =0

This is in the form ax^2+bx +c =0

where a=-1 b=0 and c=2

The discriminant is

b^2 -4ac

0^2 -4*(-1)*2

0+8

The discriminant is 8

pochemuha

If you’re looking for an equation for both of these, Bob’s rentals would be 20+2m and Bella’s would just be 6m. If you are trying to figure out how many movies it would take to be the same, set up the equation 20+2m=6m and solve. Im not exactly sure what you are asking for but I hope this helps.
