You asked:

Simplify the expression: \(x \left(x + 4\right) + 3 \left(x + 4\right)\)

MathBot Answer:

Simplified:

\[ x\left( x + 4 \right) + 3 \left(x + 4\right) = x \left(x + 4\right) + 3 x + 12 \]

$$\begin{aligned}x \left(x + 4\right) + 3 \left(x + 4\right)\\x^{2} + 4 x + 3 \left(x + 4\right)\\x^{2} + 4 x + 3 x + 12\\x^{2} + 7 x + 12\end{aligned}$$

Expanded:

\[ x\left( x + 4 \right) + 3 \left(x + 4\right) = x^{2} + 7 x + 12 \]

Factored:

\[ x\left( x + 4 \right) + 3 \left(x + 4\right) = \left(x + 3\right) \left(x + 4\right) \]
