Hello from MrBillDoesMath!

Answer:

4x^4 - 2x^3 + 4x^2 -2x + ( +\-7 + 1)

See Discussion for meaning of "+\-" symbol above

Discussion:

** The first polynomial (10x^4-2x 7) is missing an operand between 2x and 7. I have indicated it below by using (+\_), meaning I don't know what you wanted.**

(10x^4-2x +\- 7)-(6x^4+2x^3-4x^2-1) => combine like terms

(10x^4 - 6x^4) - (2x^3) - (-4x^2) + (-2x) + ( +\-7 +1) =

4x^4 - 2x^3 + 4x^2 -2x + ( +\-7 + 1)

Thank you,

MrB
