expand A(3,0,-1)B(0,-2,0)

expand

A (3, 0, - 1) B (0, - 2, 0)

3 A B, 0, 0, - 3 A B, 0, 2, 0 - 1 \cdot 0 \cdot A B, 1 \cdot 2, 0

Solution steps

A (3, 0, - 1) B (0, - 2, 0)

= (3 \cdot 0,, - 1) (0, - 2 \cdot 0,) A B

Expand

(3, 0, - 1) (0, - 2, 0) : 3, 0, 0, - 3, 0, 2, 0 - 1 \cdot 0, 1 \cdot 2, 0

= A B (3, 0, 0, - 3, 0, 2, 0 - 1 \cdot 0, 1 \cdot 2, 0)

Expand

A B (3, 0, 0, - 3, 0, 2, 0 - 1 \cdot 0, 1 \cdot 2, 0) : 3 A B, 0, 0, - 3 A B, 0, 2, 0 - 1 \cdot 0 \cdot A B, 1 \cdot 2, 0

= 3 A B, 0, 0, - 3 A B, 0, 2, 0 - 1 \cdot 0 \cdot A B, 1 \cdot 2, 0

\frac{3.0685}{x ( x + 0.2933 )}

(a + c = 40, 0) (25 a + 15 c = 7550)

\frac{2 n}{n + 4} + \frac{7}{n - 1}
