expand-4cos^2(t)-2sin(t)(2sin(t)+16)

expand

- 4 cos^{2} (t) - 2 sin (t) (2 sin (t) + 16)

- 32 sin (t) - 4

Solution steps

- 4 cos^{2} (t) - 2 sin (t) (2 sin (t) + 16)

Expand

- 2 sin (t) (2 sin (t) + 16) : - 4 sin^{2} (t) - 32 sin (t)

= - 4 cos^{2} (t) - 4 sin^{2} (t) - 32 sin (t)

Simplify

- 4 cos^{2} (t) - 4 sin^{2} (t) - 32 sin (t) : - 32 sin (t) - 4

= - 32 sin (t) - 4

\frac{( 7 x + 3 m ) ^{2}}{36}

(3 x - 2) e^{x}

(x + i x^{2})^{2}

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

\frac{2 x ^{2} + 6 x}{( x + 2 ) ( x + 4 )}
