Question

Help! Write answer in standard form.  I don't know how to subtract these.
(6x-4x^2+4) - (4x^2+5x-2+4x^3)

anonymous · Answer

Just subtract the variables that have the same bases. eg. 6x-5x and -4x^2-4x^2.
You should end up with x-8x^2-4x^3+6.
6x-5x=x
-4x^2-4x^2=-8x^2
-4x^3=-4x^3
4-(-2)=6

Remove the parentheses from the trinomial (at left).
Then distribute the negative through the entire second parentheses. Every sign inside the second parentheses will change.
Then combine like terms.
