Question

subtract (6x^3-4x+5)-(2x^3-x^2+7x-10) in descending order

Answer 1

will someone please help lol

Answer 2

I gave it a shot... can't guarantee this is right because I haven't taken a math course in a while but what I did was....
Subtract the x^3's first... so (6x^3-2x^3) = 4x^3
Then I subtracted the negative x^2 from the right side which gives us POSITIVE x^2
Then I subtracted 7x on the right from negative 4x on the left.... -11x
Then subtract negative ten from five which is (5-(-10) --> (5+10) = 15

My end result was
4x^3 + x^2 - 11x + 15

Hope that helps!
