Ah i need ! i'll give max points i can give to you.

so i'm tryna factor this equation: 2x^4-9x^3-20x^2+12x but i'm a bit stuck because for my answer i got x(-8x^3+15x^2-16x+30) i know for a fact that my answer is wrong but i need to find the roots/zeros and i'm just confuzzled.

answer:

factor   x   out of   2 x ^4   − 9x^3 -20x^2 + 12x.

x (2x^3 - 9x^2 -20x + 12)

hope this ! : )

answer:

it is 2 x^4-9 x^2 + 12x that is the answer

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
