Answer:
7x
Explanation:
First, let's factor the expression 7x² + 14x. The greatest common factor of 7x² and 14x is 7x. 7x² / 7x = x, and 14x / 7x = 2, so our factored expression becomes 7x(x + 2).
If we write our expression as a fraction now, we have
![(7x(x+2))/(x+2)](https://img.qammunity.org/2022/formulas/mathematics/middle-school/zly4iqpjmgbjaxle8458et1dj911te610j.png)
And cancelling the x + 2 in the numerator and denominator gives us the value 7x.
