Question

Expand (y + 1)(y + 4)

Answer 1

Answer:
`y^2\text{ + 5y + 4}`Explanations:

The given expression is:

(y + 1) (y + 4)

To expand the expression, each of the terms in the first bracket multiplies each term in the second bracket

The expression then becomes:

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