expand-(2(2x+9))/(9(9-y))

expand

- \frac{2 ( 2 x + 9 )}{9 ( 9 - y )}

- \frac{4 x + 18}{81 - 9 y}

Solution steps

- \frac{2 ( 2 x + 9 )}{9 ( 9 - y )}

Expand

9 (9 - y) : 81 - 9 y

= - \frac{2 ( 2 x + 9 )}{- 9 y + 81}

Expand

2 (2 x + 9) : 4 x + 18

= - \frac{4 x + 18}{- 9 y + 81}

- \frac{75 ( - 1 ) ^{\frac{1}{4}} ( 74 + 69 i )}{7754 - 5497 i}

20 i + 15 (cos (60 i) + sin (60 j))

(2 + x) 9 - x^{2}

(1 - cos (x))^{8}

4 x - (2 x + 3) (4 - 5 x) l e f t (11 x + 10 x^{2})
