Question

need some ones help on two problems PLEASE!!! one of them are simplifying (8x – 2) + (7x + 6)
and the other one is 6x^6-9x^5-3x^5
3x^3
A) =(2x^3-3x^2-1)(x^2-3x+2) needs to be completed by multiplying the trinomials.

Answer 1

can you help me ?

Answer 2

8x + 7x -2 + 6 = 15x + 4

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

Answer 3

is that both of them or just the first proble ?

Answer 4

The first and second ones

Answer 5

thank you

Answer 6

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

Answer 7

= 2x^5 - 6x^4 +4x^3 -3x^5 +9x^3 -6x^2 -x^2 +3x -2

Answer 8

can you help me Simplify:

2x2y + 7z2y - xy + 4x2y + 4z2y - xy

Answer 9

Combine like-terms.

2x^5 -3x^5 -6x^4 +4x^3 +9x^3 -6x^2 -x^2 +3x -2 (you still need to solve this by combining the like terms. I just rearranged it.)

Answer 10

2x2y + 7z2y - xy + 4x2y + 4z2y - xy

Rearrange these first.

2x2y -xy -4x2y -xy +7z2y +4z2y

xy -4x2y -xy +11z4y

0 -4x2y + 11z4y

-4x2y +11z4y
