To factor the expression \( 42v + 35 \), we need to find the greatest common factor (GCF) of the coefficients of the terms involved.
The coefficients are 42 and 35.
-
We can find the GCF:
- The prime factorization of 42 is \( 2 \times 3 \times 7 \).
- The prime factorization of 35 is \( 5 \times 7 \).
- The common factor is 7.
-
Now, we can factor out the GCF (which is 7) from the expression: \[ 42v + 35 = 7(6v + 5) \]
Thus, the factored form of \( 42v + 35 \) is: \[ \boxed{7(6v + 5)} \]
