For future reference, scientific notation is used to write really big or small numbers faster. Whatever power the ten is raised to is how many zeros are before or after the point.
Answer:
-4x^2-6x+6
(third choice)
Step-by-step explanation:
To do f(x)-g(x) we must insert the expression for f(x) and g(x) into this:
This will give us:
(8x^2-2x+3)
-(12x^2+4x-3)
--------------------
-4x^2-6x+6
Horizontally if you prefer:
(8x^2-2x+3)-(12x^2+4x-3)
Distribute and get rid of paranthesis:
8x^2-2x+3-12x^2-4x+3
Pair up like terms:
8x^2-12x^2-2x-4x+3+3
Combine the like terms:
-4x^2-6x+6
