Question

10q - 20 is equivalent to _____.


2(q - 10)
10(q - 20)
10(q - 2)

Answer 1

The given expression may be factored out by dividing both terms by the greatest common factor of the numerical coefficients which is 10. The second factor is then equal to q - 10. Therefore, the answer is the second choice, 10(q - 20). 

Answer 2

10q-20
10(q-2)

factor out 10 as it is a common factor
