To factorize the expression 4x^2 + 28x fully, we can first factor out the greatest common factor, which is 4:
4x^2 + 28x = 4(x^2 + 7x)
Next, we can look for any common factors within the parentheses. In this case, there are no common factors other than 1. Therefore, the final factorization is:
4x^2 + 28x = 4(x^2 + 7x)
