Factor the following:

2x2+9x+9

Answer: (2x+3) (x+3)

Step-by-step explanation:

Looking at this, you know that it must look something like

(? + 3) (?+3), because they must multiply to 9. The? s must multiply to 2x^2, the most plausible values being 2x and x, ending us up with (2x+3) (x+3)

(x + 3) (2x + 3)

Step-by-step explanation:

2x^2+9x+9

2x^2 + 3x + 6x + 9

x (2x + 3) + 3 (2x + 3)

(x + 3) (2x + 3)
