Simplify by combining like terms 2rs 7r6s 9rs6 9rs6 7rs

Simplify by combining like terms. (2rs - 7r^6s - 9rs^6) - (9rs^6 - 7rs + 2 r^6s)

Solution

Given that

(2rs - 7r⁶s - 9rs⁶) - (9rs⁶ - 7rs + 2r⁶s) = 2rs - 7r⁶s - 9rs⁶ - 9rs⁶ + 7rs - 2r⁶s

= 9rs - 9r⁶s - 18rs⁶

Therefore ,

  (2rs - 7r⁶s - 9rs⁶) - (9rs⁶ - 7rs + 2r⁶s) = 9rs - 9r⁶s - 18rs⁶
