Identify the factors of 9x2 + 30x + 25. a) (3x − 5)(3x − 5) b) (3x + 5)(3x + 5) c) (9x + 5)(x + 5) d) (9x − 5)(x − 5)

Selection B is appropriate.


The signs of the coefficients tell you the binomial factors must have both signs positive (selections B and C only). Selection B produces an x-term that is 15x+15x=30x (as we want); selection C produces an x-term that is 45x+5x=50x (not what we want).
