expand (sin(x)-3)(sin(x)+1)

expand

(sin (x) - 3) (sin (x) + 1)

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

Solution steps

(sin (x) - 3) (sin (x) + 1)

Apply FOIL method

(sin (x) - 3) (sin (x) + 1) : sin^{2} (x) - 2 sin (x) - 3

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

\frac{y ( x ^{2} + y ^{2} ) ^{2}}{x ^{5}}

(x + \frac{1}{3})^{3} \cdot (x + \frac{2}{9})^{2}

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

\frac{727 ( - x + 3 )}{114}

96 (s + s^{'})^{10}
