expand A(3,-1)B(-2,-4)

expand

A (3, - 1) B (- 2, - 4)

- 3 A B, 2, - 3 A B, 4 + 1 \cdot 2 A B, 1 \cdot 4

Solution steps

A (3, - 1) B (- 2, - 4)

= (3, - 1) (- 2, - 4) A B

Expand

(3, - 1) (- 2, - 4) : - 3, 2, - 3, 4 + 1 \cdot 2, 1 \cdot 4

= A B (- 3, 2, - 3, 4 + 1 \cdot 2, 1 \cdot 4)

Expand

A B (- 3, 2, - 3, 4 + 1 \cdot 2, 1 \cdot 4) : - 3 A B, 2, - 3 A B, 4 + 1 \cdot 2 A B, 1 \cdot 4

= - 3 A B, 2, - 3 A B, 4 + 1 \cdot 2 A B, 1 \cdot 4

(4 x^{3} - 4 x^{4} - 3) d x

\frac{( 2 s + 1 ) ( s + 2 )}{6 s ^{4} + 35 s ^{3} + 14 s ^{2} + 20 s + 6}

\frac{( x - 4 ) ( x + 8 )}{( x - 6 ) ^{2}}

\frac{x ( x - 1 )}{x - 2}

(4 - 3 i)^{5}
