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

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

(2 x + 4) (x)

(\frac{3 a}{2} - \frac{2 b}{3})^{2}

\frac{3 ( y + 2 )}{2}

(f \circ g) (x - 5)

(7 + 22) (7 - 22)
