2X%5E3+%2B18X%5E2+-+5X+-+45+

Factor the first two terms by taking out 2x%5E2

2X%5E2%28X+%2B9%29+-+5X+-+45+

Factor the last two terms by taking out -5
(Watch out for a sign change when you factor out a
negative!)

2X%5E2%28X+%2B9%29+-+5%28X+%2B+9%29+

Factor out %28X%2B9%29

%28X+%2B9%29%282X%5E2+-+5%29+
