Question

solve AC method
3x³-5x²-2x

Answer 1

step by step

Answer 2

factor out an x first off

Answer 3

u can email to me if easier

Answer 4

a*c = 6; but there are no factor of 6 that subtract to.....ohyes there are :)

Answer 5

aint gonna have internet after 7..

Answer 6

1) after factoring out the "x" we get; 3x^2 -5x -2

2) set it up as tho it CAN factor:

(x /3) (x /3)

3) look at last sign...its a (-); we need a (+)(-)..also means we subtract factors to get the middle

4) look at middle sign; its a (-)...the largest # gets the (-)

5) finish setup

(x- L/3) (x+S/3) L = large, S = small

6) a*c...3*2 = 6; factors of 6 then...

1,6 ... 6-1 = 5; dont need to go further we got em..

7) plug into setup

(x -6/3) (x+1/3)

8) reduce till you cant reduce no more...

6/3 = 2...stop!!

1/3 = 1/3....stop!!

fill it in :)

(x-2)(x+1/3) <- if theres a fraction, put the bottom in front like this:

(x-2) (3x+1)

Answer 7

dont forget the "x" you factored to begin with..

x(x-2)(3x+1)

Answer 8

ty for your help

Answer 9

im being told by professor that this is not correct we are to rearrange first then factor GCF
