factor cos^2(x)-sin^2(y)

factor

cos^{2} (x) - sin^{2} (y)

(cos (x) + sin (y)) (cos (x) - sin (y))

Solution steps

cos^{2} (x) - sin^{2} (y)

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

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

= (cos (x) + sin (y)) (cos (x) - sin (y))

9 \cdot 3^{- x}

5 x^{3} - 55 x^{2} + 120 x

(2 x + 6)^{6}

9 q + 1^{3}

8^{n + 2} \cdot 1 2^{n - 3}
