(6x+1)(x^2-9x+5)

(2x^4+3)(4x^3+2)

(12y^3+8y^2+20y)divided 2y

(6x^2-25x-10) divided by (3x+2)

(8x-5)+(7x+4)

(5x -3.6)-(4x+1.2)

(3x^2+3x)+(4x+40

(6x-6)-(3x -3)

Find the product of (x^2-3x+5)with the quotient of (10x^6-15x^5-5x)

**Henry**, Sunday, December 11, 2011 at 6:53pm1. (6x+1)(x^2 - 9x + 5).

Multiply 6x by each term in the 2nd

parenthesis. Then multiply 1 by each term in the 2nd parenthesis:

6x^3 -54x^2 + 30x + x^2 - 9x + 5,

Combine like-terms:

6x^3 - 53x^2 +21x + 5.

2. Same procedure as #1.

3, (12y^3 + 8y^2 + 20y) / 2y.

Divide each term by 2y:

6y^2 + 4y + 10.

4.(6x^2-25x-10) / (3x+2) = 2x-9 + Re

-2x+8. I used Synthetic(Long) division.

It is difficult to show steps here.

5. (8x-5) + (7x+4) =

8x - 5 + 7x + 4,

Combine like-terms:

15x -1.

6. (5x-3.6)- (4x+1.2) =

5x - 3.6 - 4x -1.2,

x - 4.8.

7. Same procedure as #5.

8. Same procedure aqs #6.
