Answer:
3x^5 -2x^4 -x^2 +x -21
Step-by-step explanation:
We need to subtract g(x) from f(x)
f(x) = 3x^5 +6x^2 -5
g(x) = 2x^4 +7x^2 -x+16
f(x) -g(x) = 3x^5 +6x^2 -5 - (2x^4 +7x^2 -x+16)
Distribute the minus sign
3x^5 +6x^2 -5 - 2x^4 -7x^2 +x-16
I like to line them up vertically
3x^5 +6x^2 -5
- 2x^4 -7x^2 +x-16
---------------------------------------
3x^5 -2x^4 -x^2 +x -21
G(x) − f(x) = x^2 - (<span> 3x + 5)
</span>g(x) − f(x) = x^2 - 3x - 5
<span>
answer is A. first one
</span>x^2 - 3x - 5
30% is needed because i believe it is i am really trying hope u get it right <span />
