Question 34: Perform the calculation \(\begin{array}{l} \left[ {5{{(x + 2y)}^6} – 6{{(x + 2y)}^5}} \right]:2{(x + 2y)^4} \end{array}\) we get

\(\begin{array}{l} \left[ {5{{(x + 2y)}^6} – 6{{(x + 2y)}^5}} \right]:2{(x + 2y)^4}\\ = 5{(x + 2y)^6}:2{(x + 2y)^4} – 6{(x + 2y)^5}:2{( x + 2y)^4}\\ = \frac{5}{2}{(x + 2y)^2} – 3(x + 2y) \end{array}\)
