Question

simply (3x +2y)² - (3x-2y)²​

Answer 1

Answer:

               24xy

Step-by-step explanation:

                 

(3x +2y)² - (3x-2y)²​

[(3x)²+ (2y)² + 2×3x×2y] - [(3x)² + (2y)² - 2×3x×2y]

{By using the formula (a + b)² = a² + b² + 2ab

  And (a - b)² = a² + b² - 2ab}           (Hope u understood this step)

Now next step:

[(3x)²+ (2y)² + 2×3x×2y] - [(3x)² + (2y)² - 2×3x×2y]

[9x² + 4y² + 12xy] - [9x² + 4y² - 12xy]     (Hope u understood)

Now remove brackets by multiplying minus sign

9x² + 4y² + 12xy - 9x² - 4y² + 12xy

12xy + 12xy            (By cancelling terms)

24xy

Answer 2

Answer:

3x+2y)2-(3x-2y) 2

Step-by-step explanation:

3x+2y)2-(3x-2y) 2

3x+2y=5

3x-2y2=4

3x=1
