Question

Find the product of (x+4) (x+1)

Answer 1

`x^2\text{ }+\text{ 5x + 4}`Step-by-step explanation:
`(x+4)(x+1)`

Expanding:

`\begin{gathered} x(x\text{ + 1) + 4 (x + 1)} \\ x^2\text{ + x + 4x + 4} \end{gathered}`

collect like terms:

`\begin{gathered} x\text{ + 4x = 5x} \\ x^2\text{ }+\text{ 5x + 4} \end{gathered}`
