do you mean 9x^2+12x+4?

Answer 2

9x^2 + 12x + 4
9x^2 + 6x + 6x + 4
3x(3x + 2) + 2(3x + 3)
we got
(3x+2)(3x+2)
(3x+2)^2

Answer 3

satisfied or not with my solution

Answer 4

satisfied! thank you so much!

Answer 5

Whenever I see that the first and last terms are perfect squares, I immediately look to see if it's of the form\[(ax+b)^{2}=a^{2}x^{2}+2abx+b^{2}\]
In this case, a=3, b=2.

2abx would equal 2(3)(2)x = 12x.

So \[(3x+2)^{2}\]works.
