Using <span>Descartes' rule of signs.
There are 4 changes of signs of coefficients:
+ to - (+x^6-x^5)
- to + (-x^4+4x^3)
+ to - (+4x^3-12x^2)
- to + (-12x^2+12)
Therefore, there are 4,2 or 0 positive roots </span><span><span>at most</span>. So it must be the third answer.

Is there another part to this question? What should we answer?
The value of y from the expression is y = 3/2(j-k)
<h3>Subject of formula</h3>
Given the expression below
2/3y + k = j.
Subtract k from both sides
2/3y = j - k
Divide both sides by 2/3
(2/3y)/2/3 = (j-k)/(2/3)
y = 3/2(j-k)
Hence the value of y from the expression is y = 3/2(j-k)
