expand (2sin(x)+1)(2sin(x)-1)

expand

(2 sin (x) + 1) (2 sin (x) - 1)

4 sin^{2} (x) - 1

Solution steps

(2 sin (x) + 1) (2 sin (x) - 1)

Apply Difference of Two Squares

(2 sin (x) + 1) (2 sin (x) - 1) : 4 sin^{2} (x) - 1

= 4 sin^{2} (x) - 1

(e^{t} + t e^{t})^{2}

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

2 x l e f t (3 x^{2} - 5 x + 1)

4^{2}

\frac{x - 29}{( x - 2 ) ^{2}}
