Question

Let f(x) = (8x^3) – (22x^2) – 4 and g(x) = 4x – 3 Find f(x)/g(x) .

Answer 1

use synthetic division process

Answer 2

I haven't learned that yet I'm supposed to be using polynomial long division but the lesson doesn't explain very well. Some of the answers have fractions in them and i don't know why.

Answer 3

2x^2 2x^2 -4x
------------------ ------------------
4x – 3 ) 8x^3 – 22x^2 – 4 4x – 3 ) 8x^3 – 22x^2 – 4
8x^3 - 6x^2 ==> 8x^3 - 6x^2 => ...?
----------------- -----------------
-16x^2 +0x -16x^2 +0x
-16x^2 + 12x
--------------
-12x - 4

Answer 4

these are the answers i have
2x^2 – 4x – 3 – [(13/4x-3)]

2x^2 – 4x – 3 – [(4x-3)/(13)]

2x^2 – 7x – 1

2x^2 – 7x – 5 + [(x-4)/(4x-3)]

Answer 5

''Some of the answers have fractions in them and i don't know why.''
=> It is because it may not be divisible by 4x-3

I just left one step there for you.
