Answer 1

$\huge{Hey \ Dude}$


Here is your answer

Final result :

(-9x - 11y) • (x + 19y)

Step by step solution :

Step  1  :

Equation at the end of step  1  :

(16 • ((x - y)2)) - 25 • (x + 3y)2

Step  2  :

Equation at the end of step  2  :

16 • (x - y)2 - 25 • (x + 3y)2

Answer 2

Step-by-step explanation:

16(x+y)2-25(x-3y)2

(19y - x) • (9x - 11y)

(16 • ((x + y)2)) -  25 • (x - 3y)2

16 • (x + y)2 -  25 • (x - 3y)2

-9x2 + 182xy - 209y2  =   -1 • (9x2 - 182xy + 209y2)

(19y - x) • (9x - 11y)
