Step-by-step explanation:

$(\sin{x} - \sin{y})(\sin{x} + \sin{y}) = \sin^2{x} + \sin{x}\sin{y} - \sin{x}\sin{y} - \sin^2{y}$

$= \sin^2{x} - \sin^2{y}$

Doss [256]

Answer:

the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.
