Step-by-step explanation:

All the terms in this polynomial are divisible by 3. Factor 3 out of this polynomial:

Now, factor inside the parentheses by grouping:

We knew to split the +2x up into -1x and 3x because -1 and 3 multiply to get -3, which is the last value in the polynomial.

Therefore, the final factored polynomial is
.
This would be ( using the Pythagoras theorem) = sqrt (3^2 + 4^2) = sqrt 25
= 5 units (answer).
