factor the expression using the greatest common factor. 50u - 20

Answer 1

To factor the expression 50u - 20 using the greatest common factor (GCF), we first need to find the GCF of the coefficients, which are 50 and 20.
The prime factorization of 50 is 2 * 5 * 5, and the prime factorization of 20 is 2 * 2 * 5.
The common factors are 2 and 5. The greatest common factor is 2 * 5 = 10.
Dividing both terms in the expression by 10, we get:
50u/10 - 20/10 = 5u - 2.
Therefore, the factored form of the expression 50u - 20 using the greatest common factor is 10(5u - 2).
