Question

find the following products( 3x + 2a) (3x- 2a)​

Answer 1

Step-by-step explanation:

Formula= (a + b) (a - b) =(a² - b²)

Solution= (3x + 2a) (3x - 2a)

=(3x) ² - (2a)²

=9x² - 4a²

Answer 2

Answer:

using(a−b)(a+b)=a2−b2

For the above expression, keeping a=3x and b=2, we get

(3x+2)(3x−2)=(9x2−4)
