Answer 2

thank you :) can you help me on my problem?

Answer 3

@confluxepic

Answer 4

\[(x-2)(x^{2}+3x-5)\]

Answer 5

Do you know how to distribute.

Answer 6

This could help.

Answer 7

that didn't make much sense, can you explain

Answer 8

For example lets multiply (2+x)(3+x).
You can use the FOIL method.
First multiply 2 and 3. We get 6.
Next multiply 2 and x. We get 2x.
Then multiply x and 3. We get 3x.
After that multiply x and x. We get x^2.
Put them together.
We get \[x^{2}+2x+3x+6\]
Add the like terms and we get\[x^{2}+5x+6\]
That is how you distribute.

Answer 9

that makes sense, thank you! so for this problem, (x-2)(x^2+3x-5)
multiply 2 and 2 and get 4 2 and 3 and get 6 2 and 5 and get ten
so is it 4+6+10

Answer 11

\[(x)(x^{2})+(x)(3x)+(x)(-5)+(-2)(x^{2})+(-2)(3x)+(-2)(-5)\]

Answer 12

\[(x^{3})+(3x^{2})+(-5x)+(-2x^{2})+(-6x)+(10)\]

Answer 13

\[(x^{3})+(x^{2})+(-11x)+(10)\]

Answer 14

That is the simplified equation.

Answer 15

okay, so what is the next step

Answer 16

@confluxepic

Answer 17

\[x^{3}+x^{2}-11x+10\]

Answer 18

That's the answer.
