The first step to solving this is to write 7x as a difference x² + 9x - 2x - 18 next you need to factor out x from the expression x × (x + 9) - 2x - 18 then you'll need to factor out -2 from the expression x × (x + 9) - 2 (x + 9) lastly,, you need to factor out x + 9 from the expression (x + 9) × (x - 2) this means that the correct answer to your question is (x + 9) × (x - 2). let me know if you have any further questions :)
