Question

Factorise fully 3x-9x^2

Answer 1

Answer:

$3x(1 - 3x)$

Step-by-step explanation:

We can factor the expression by using the common factor.

Pull out 3x from the expression.

$3x - 9 {x}^{2} \\ 3x(1 - 3x)$

Common Factor is similar to dividing by the term we pull out. When we pull out the term, we divide the whole expression and keep the term out of the expression.
