Question

(2 x + y) (2 x - y) =
(p - 3 q) (p +3 q)=
(3 m + n) (3 m - n)=​

Answer 1

Explicación paso a paso:

(2 x + y) (2 x - y) = 4x²-y²

(p - 3 q) (p +3 q)= p²-9q²

(3 m + n) (3 m - n)=9m²-n²

Answer 2

Respuesta:

Explicación paso a paso:

(2 x + y) (2 x - y) = ( 2x )² - ( y )²

(p - 3 q) (p +3 q) = ( p )² - ( 3q )²

(3 m + n) (3 m - n) =​ ( 3m )² - ( n )²
