Question

9r^2+15r+6
factored out with work

Answer 1

would the solution (9r+3)(r+2)
be correct

Answer 2

not quite 18r+3r = 21r not 15r

Answer 3

Let's work it out.

(9r + 3)(r + 2)
First: \[9r*r = 9r ^{2}\]
Outside: 9r*2=18r
Inside: 3*r = 3r
Last: 3*2=6
\[9r ^{2}+18r + 3r + 6 = 9r^{2} + 21r + 6\]

Answer 4

So, not quite. As dumbcow beat me to it. :)

Answer 5

9*6=54
9+6=15
(9r+6)(9r+9)
reduce
(3r+2)(3r+3)

Answer 6

ohhhh

Answer 7

actually i forgot you could factor out a 3 first
3(3r^2 +5r +2)
=3(3r+2)(r+1)

Answer 8

ok lol
