expand (2-tan(x))^2

expand

(2 - tan (x))^{2}

4 - 4 tan (x) + tan^{2} (x)

Solution steps

(2 - tan (x))^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

2^{2} - 2 \cdot 2 tan (x) + tan^{2} (x) : 4 - 4 tan (x) + tan^{2} (x)

= 4 - 4 tan (x) + tan^{2} (x)

(c + d) (c - d)

\frac{1}{( n + 3 ) ( n + 2 )}

\frac{5 ( x + h ) + 1 - 5 x + 1}{h}

3 e^{x} + 10 (3 x^{2} ln (x) + x^{2})

\frac{2}{s ^{3} ( s ^{2} + 1 )}
