Question

1) (A + 3 )² 2) (B - 4)²

3 (2R + 1)² 4) (3B - 3 )²

5) (3B² + 3C)² 6) ( 4B³ +2R ) . ( 4B³ - 2R)​

Answer 1

1) (A + 3 )² = (aplicaremos a distributiva)

  (A + 3 )(A + 3 )² =

  A² + 6A + 9

2) (B - 4)²  =

   (B - 4)(B - 4) =

   B² - 8B + 16

3) (2R + 1)² =

   (2R + 1)(2R + 1) =

   4R² + 4R + 1

4) (3B - 3 )²  =

   (3B - 3 )(3B - 3 ) =

   9B² - 18B + 9

5) (3B² + 3C)² =

   (3B² + 3C)(3B² + 3C) =

   9B^4 + 18B²C + 9C²

6) ( 4B³ + 2R ) . ( 4B³ - 2R)​ =

    16B^6 - 4B³R + 4B³R - 4R²

    16b^6 - 4R²
