expand A(4,-2,3)B(5,-4,2)

expand

A (4, - 2, 3) B (5, - 4, 2)

4 A B, 5, - 4 A B, 4, 2 - 2 A B, 3 \cdot 5, 2, 3 \cdot 4, 2

Solution steps

A (4, - 2, 3) B (5, - 4, 2)

= (4, - 2 \cdot 3,) (5, - 4 \cdot 2,) A B

Expand

(4, - 2, 3) (5, - 4, 2) : 4, 5, - 4, 4, 2 - 2, 3 \cdot 5, 2, 3 \cdot 4, 2

= A B (4, 5, - 4, 4, 2 - 2, 3 \cdot 5, 2, 3 \cdot 4, 2)

Expand

A B (4, 5, - 4, 4, 2 - 2, 3 \cdot 5, 2, 3 \cdot 4, 2) : 4 A B, 5, - 4 A B, 4, 2 - 2 A B, 3 \cdot 5, 2, 3 \cdot 4, 2

= 4 A B, 5, - 4 A B, 4, 2 - 2 A B, 3 \cdot 5, 2, 3 \cdot 4, 2

\frac{x ^{4 n} + x ^{2 n} - 2}{( x ^{n} - 1 ) ( x ^{n} + 1 )}

2 x (3 x^{2} + 2) - 5

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

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