Question 11. Really don’t understand, if you have an explanation I need one thank you

Answer 1

Answer:

m > 3 for 2 solutions.

m = 3 for one solution.

Step-by-step explanation:

mx^2 - 2mx + 3 = 0

For 2 solutions   the discriminant b^2 - 4ac > 0 so we have

(-2m)^2 - 4*m* 3 > 0

4m^2 - 12m > 0

4(m^2 - 3m) > 0

m^2 - 3m > 0

m(m - 3) > 0

m > 3  - this is the result for 2 solutions.

For one solution the discriminant = 0

so m(m - 3) = 0

and  m = 3 for 1 solution.
