Let f(x) = 3x2 + x - 3 and g(x) = x2 - 5x + 1. Find f(x) - g(x).

okay so what you do is this.

you have the equations, they want you to subtract them.

But I'm guessing you mean 3x^2 right? and x^2

Answer 4

yes I do

Answer 5

So if that is so:

3x^2 + x-3 - x^2-5x+1
combine similar terms

you get

2x^2 -4x - 2

Answer 6

f(x) – g(x)
f(x) = 3x^2 + x – 3
g(x) = x^2 – 5x + 1
so

3x^2 + x – 3 - (x^2 – 5x + 1)
3x^2 + x - 3 - x^2 +5x -1
Combine common factors
3x^2 - x^2
x + 5x
- 3 - 1
And you get:
2x^2 + 6x - 4

Answer 7

lol yana how did you get that?

Answer 8

Lol, sorry!! I hate those things. I don't know why it turned out to be that way!! Sorry again!!

Answer 9

ahh you multiplied by -1
