Question

Fing the length of the missing side

Answer 1

The area is given as

`x^2-6x+9`

We can either divide the area by the side given and get the other side

OR

We can simply factorize the area and hence determine the two factors that were multiplied together. Note that one factor has already been given (that is x-3).

To factorize the polynomial;

`\begin{gathered} x^2-6x+9 \\ =(x-3)(x-3) \end{gathered}`

This means the other side is also (x - 3)
