Question

How many real number solutions does the quadratic below have? y=2x^2-10x+6

Answer 1

i think its 2 real number

Explanation:

Answer 2

2 real number solutions.

Explanation:

You check the value of the discriminant b^2 - 4ac.

Here it = (-10)^2 - 4*2* 6)

= 100 - 48

= 52. (Positive)

This means that it has 2 real number solutions.

If the discriminant = 0 it has one real number solution and if negative it has no real number solutions.
