Mathematics

Lyrx [107]3 years ago

Answer:

The coefficient of the 2nd term of trinomial is 18.

Step-by-step explanation:

You can expand in a faster way by using the formula, (a+b)² = a²+2ab+b² :

(3x+3)² = (3x)² + 2(3x)(3) + 3²

= 9a² + 18a + 9

OR

You can expand it by doing step by step :

(3x+3)² = (3x+3)(3x+3)

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

= 9x² + 9x + 9x + 9

= 9x² + 18x + 9
