G

3(a + 2)(a + 3)

= 3(a^2 + 3a + 2a + 6)

= 3(a^2 + 5a + 6)

= 3a^2 + 15a + 18

That's not 3a^2 + 9a + 6.

G

3a^2 + 9a + 6

try using the quadratic formula to factor that out, or complete the square.

Almost. That last 3 should be a 1:Dominic said:Factor: 3a^2 + 9a + 6.

My answer is :

3(a + 2)(a + 3)

Is this correct?
