5. what does descartes's rule of signs tell you about the real roots of the polynomial?

–2x3 + 3x2 – 5x – 2 = 0 (1 point)
there is one positive root and either 2 or 0 negative roots.
there are either 2 or 0 positive roots and there are either 2 or 0 negative roots.
there is one positive root and one negative root.
there are either 2 or 0 positive roots and one negative root.

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
