k(x^2)-3x+2=0
When the discriminant of the quadratic formula is greater than zero, then you will have two real roots.
The discriminant is b^2 -4ac
From the above equation, a = k, b = -3, and c = 2.
Plugging in you get
(-3)^2 – 4(k)(2)
= 9 – 8k
Set this to be greater than zero and solve for k.
9 – 8k > 0
Add 8k to both sides
9 > 8k
Divide both sides by 8
9/8 > k
Flip
k < 9/8

You COULD do your own homework. You could even put the formula into Excel or Lotus.
You might even draw a parabola.
