Expanding the expression (3x + 2)² we will get 9x² + 12x + 4

How to expand the expression?

Here we want to expand the expression (3x + 2)² to get a standard quadratic polynomial.

Remember the rule:

(a +b)² = a² + 2ab + b²

Now we can apply this expansion to the given expression, we will get:

(3x + 2)² = (3x)² + 2*(3x)*(2) + (2)²

= 9x² + 12x + 4

That is the expanded expression.
