divide -3x^2-4x^2+4x+3 by x-2

-3x^2 -10x -16  -29/(x-2)

Step-by-step explanation:

-3x^3-4x^2+4x+3

We can do synthetic division

    -3    -4    4   3

2

Bring the first term down

    -3    -4    4   3

2

    -3

Multiply -3 times 2

    -3    -4    4   3

2           -6

    -3

Add -4 and -6

    -3    -4    4   3

2           -6

    -3    -10

Multiply 2 *-10

    -3    -4      4   3

2           -6    -20

    -3    -10

Add 4 and -20

   -3    -4      4       3

2           -6    -20

    -3    -10    -16

Multiply the 2 by -16

   -3    -4      4       3

2           -6    -20  -32

    -3    -10    -16  -29

The result is -3x^2 -10x -16  -29/(x-2)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

9 x 8 divided by (5-3)=36
