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

expand

- 2 (x - \frac{3 π}{4})

- 2 x + \frac{3 π}{2}

Solution steps

- 2 (x - \frac{3 π}{4})

Apply the distributive law:

a (b - c) = ab - a c

a = - 2, b = x, c = \frac{3 π}{4}

= - 2 x - (- 2) \frac{3 π}{4}

Apply minus-plus rules

- (- a) = a

= - 2 x + 2 \cdot \frac{3 π}{4}

2 \cdot \frac{3 π}{4} = \frac{3 π}{2}

= - 2 x + \frac{3 π}{2}

\frac{( x + 3 ) ( x + 5 )}{2}

\frac{( - x + 15 ) ( x - 10 )}{2}

\frac{x ^{2}}{( x - 5 ) ^{2} ( x + 1 )}

- \frac{3 ( n ^{2} + 14 )}{2 n - 6}

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