Answer:

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

Step-by-step explanation:

9x^2+12x+4 =9x² + 6x + 6x + 2*2

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

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

So the sign should be positive

Answer:

Because if you were to distribute it back into the original equation you were given it would distribute back into 9x^2-12x+4. Your signs are wrong. So change it to (3x+2) (3x+2)

Step-by-step explanation: change your signs in your answer you gave to positive. :)

Alchen [17]
