expand-1+(-2)(x-(3pi)/4)

expand

- 1 + (- 2) (x - \frac{3 π}{4})

- 1 - 2 x + \frac{3 π}{2}

Solution steps

- 1 + (- 2) (x - \frac{3 π}{4})

Expand

(- 2) (x - \frac{3 π}{4}) : - 2 x + \frac{3 π}{2}

= - 1 - 2 x + \frac{3 π}{2}

\frac{1 - r}{( x - r ) ( x - 1 )}

\frac{2 ( 1 + 21 )}{5}

(1 + e^{x} - 1)^{2}

(sin (ln (2 x)) - cos (ln (2 x)))^{2}

\frac{7 + 1}{3}
