Question

3x is a factor of 3x^2-27x, what is the other factor

Answer 1

$$\huge 3x^2-27x$$

Answer 2

\[3x^2-27x\]\(=x(3x-27)\)\[=3x(x-9)\]

Answer 3

So we know that \(3x\) is one of the factors of \(3x^2-27x\).
\(3x^2\) is \(x\) times \(3x\) and \(27x\) is \(9\) times \(3x\).
So we can express \(3x^2-27x\) as \(x\times3x-9\times3x\).
Take out the common factor and we have \(3x(x-9)\).
Therefore its other factor is \(x-9\). :)
