Answer:

The answer is

( x + 7)( x - 5)

Step-by-step explanation:

x² + 2x - 35

First write 2x as a difference

That's

x² + 7x - 5x - 35

Factor out x from the expression

We have

x( x + 7) - 5x - 35

Factor out - 5 from the expression

That's

x( x + 7) - 5( x + 7)

Factor out x + 7 from the expression

We have the final answer as

( x + 7)( x - 5)

Hope this helps you
