expand (2-3sin(x))^2

expand

(2 - 3 sin (x))^{2}

4 - 12 sin (x) + 9 sin^{2} (x)

Solution steps

(2 - 3 sin (x))^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(2 - 3 sin (x))^{2} = 2^{2} - 2 \cdot 2 \cdot 3 sin (x) + (3 sin (x))^{2}

= 2^{2} - 2 \cdot 2 \cdot 3 sin (x) + (3 sin (x))^{2}

Simplify

2^{2} - 2 \cdot 2 \cdot 3 sin (x) + (3 sin (x))^{2} : 4 - 12 sin (x) + 9 sin^{2} (x)

= 4 - 12 sin (x) + 9 sin^{2} (x)

\frac{k}{s ( s + 1 ) ( s + 2 )}

(40 + \frac{40}{ln ( 4 x ^{2} + 40 )}) (x)

4 (1 + 3)

(e^{- α a_{1}} - 1) (e^{- β b_{1}} - 1)

\frac{( x ^{4} )}{( 4 ( x ^{2} + 1 ) )}
