expand A(1,-2)B(5,-5)

expand

A (1, - 2) B (5, - 5)

1 \cdot A B, 5, - 1 \cdot A B, 5 - 2 \cdot 5 A B, 2 \cdot 5

Solution steps

A (1, - 2) B (5, - 5)

= (1, - 2) (5, - 5) A B

Expand

(1, - 2) (5, - 5) : 1, 5, - 1, 5 - 2 \cdot 5, 2 \cdot 5

= A B (1, 5, - 1, 5 - 2 \cdot 5, 2 \cdot 5)

Expand

A B (1, 5, - 1, 5 - 2 \cdot 5, 2 \cdot 5) : 1 \cdot A B, 5, - 1 \cdot A B, 5 - 2 \cdot 5 A B, 2 \cdot 5

= 1 \cdot A B, 5, - 1 \cdot A B, 5 - 2 \cdot 5 A B, 2 \cdot 5

\frac{2 ( - 1 ) ^{k} + 2 \cdot 3 ^{1 + k} + 3 ( - 1 ) ^{k - 1} + 1}{2}

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

\frac{s + 1}{s ( s + 2 )}

(x + (\frac{1}{x})) \cdot (x - (\frac{1}{x}))

\frac{1}{2} (θ + \frac{sin ( 2 θ )}{2})
