+%285x%5E3%2B4x-x%5E2%29+-+%282x-3x%5E2%2B5x%5E3%29+
First ... order each piece in DESENDING powers
+%285x%5E3-x%5E2%2B4x%29+-+%285x%5E3-3x%5E2%2B2x%29+
Distribute the negative across the second quantity ... in other words, change the signs.
+5x%5E3+-x%5E2+%2B4x+-5x%5E3+%2B3x%5E2+-2x+
5x^3 cancels
+-x%5E2+%2B4x+%2B3x%5E2+-2x+
Add the x^2
+2x%5E2+%2B4x+-2x+
add the x
+2x%5E2+%2B2x+
DONE
