Factorise:
`x (x +3)+ 5 (x +3)`

Answer

To factorise the expression \( x(x + 3) + 5(x + 3) \), follow these steps:

### Step 1: Identify the common factor
In the expression \( x(x + 3) + 5(x + 3) \), we can see that both terms contain the common factor \( (x + 3) \).

### Step 2: Factor out the common factor
We can factor out \( (x + 3) \) from both terms:
\[ x(x + 3) + 5(x + 3) = (x + 3)(x + 5) \]

### Step 3: Write the final factorised form
Thus, the factorised form of the expression is:
\[ (x + 3)(x + 5) \]

### Summary of the Factorisation
The expression \( x(x + 3) + 5(x + 3) \) can be factorised to:
\[ (x + 3)(x + 5) \]
