Subtract and write in standard form
(8x – 6x3 + 5x2) - (2x2 + 2x - 7x3)

  x^3 +3x^2 +6x

Step-by-step explanation:

Eliminate parentheses using the distributive property. Collect terms. Standard form has the exponents decreasing.

  = 8x -6x^3 +5x^2 -2x^2 -2x +7x^3

  = x^3(-6 +7) +x^2(5 -2) +x(8 -2)

  = x^3 +3x^2 +6x
