6 step unsure of why 15x is now 5(3x-1)
Answer provided by our tutors
The common factor was 5. You will see that if you multiply it back, you will get the original expression
5*(3x-1) = 15x-5 -- so these are equivalent expressions.
The expression is factored, so that it could possibly later be reduced with factors in the denominator
