expand A(-2,-pi/3)

expand

A (- 2, - \frac{π}{3})

- 2 A, - \frac{π}{3} A

Solution steps

A (- 2, - \frac{π}{3})

= (- 2, - \frac{π}{3}) A

Apply the distributive law:

a (b - c) = ab - a c

a = A, b = - 2,, c = \frac{π}{3}

= A (- 2,) - A \frac{π}{3}

Apply minus-plus rules

+ (- a) = - a

= - 2 A, - \frac{π}{3} A

\frac{x ^{2} + 2 x - 20}{( x - 4 ) ( x - 6 )}

\frac{x ^{2} ( x + 1 ) ^{3}}{( x - 7 ) ( x + 3 ) ^{2} ( - x ^{2} - 1 )}
