Questions: (3r^3 - 12r^2 - 63r - 45) + (3r + 6)

Transcript text: $\left(3 r^{3}-12 r^{2}-63 r-45\right)+(3 r+6)$

Solution

Solution Steps

Step 1: Define the Expression

We start with the expression $ (3r^{3} - 12r^{2} - 63r - 45) + (3r + 6) $.

Step 2: Combine Like Terms

Next, we combine the like terms in the expression. The terms involving $ r^{3} $ and $ r^{2} $ remain unchanged, while we combine the linear terms $ -63r + 3r $ and the constant terms $ -45 + 6 $.

Step 3: Simplify the Expression

After combining the like terms, we simplify the expression to obtain $ 3r^{3} - 12r^{2} - 60r - 39 $.

Final Answer

$\boxed{3r^{3} - 12r^{2} - 60r - 39}$
