Answer:
4x² + 4x + 5
Step-by-step explanation:
Note that (f - g)(x) = f(x) - g(x), thus
f(x) - g(x)
= 5x² - 3 - (x² - 4x - 8 ) ← distribute parenthesis by - 1
= 5x² - 3 - x² + 4x + 8 ← collect like terms
= 4x² + 4x + 5
For this case we have the following subtraction:
We can rewrite the subtraction in an easier way.
We have then:
Then, by doing associative property we have:
Answer:
The value of the subtraction is given by:
Answer:
B
Step:
The general equation for linear is y=mx+b
So all is linear except B
