expand A(3,-3,2)B(-18,1,-9)

expand

A (3, - 3, 2) B (- 18, 1, - 9)

- 3 A B, 18, 1, - 3 A B, 9 + 3 A B, 2 \cdot 18, 1, 3, 2 \cdot 9

Solution steps

A (3, - 3, 2) B (- 18, 1, - 9)

= (3, - 3 \cdot 2,) (- 18 \cdot 1,, - 9) A B

Expand

(3, - 3, 2) (- 18, 1, - 9) : - 3, 18, 1, - 3, 9 + 3, 2 \cdot 18, 1, 3, 2 \cdot 9

= A B (- 3, 18, 1, - 3, 9 + 3, 2 \cdot 18, 1, 3, 2 \cdot 9)

Expand

A B (- 3, 18, 1, - 3, 9 + 3, 2 \cdot 18, 1, 3, 2 \cdot 9) : - 3 A B, 18, 1, - 3 A B, 9 + 3 A B, 2 \cdot 18, 1, 3, 2 \cdot 9

= - 3 A B, 18, 1, - 3 A B, 9 + 3 A B, 2 \cdot 18, 1, 3, 2 \cdot 9

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

(1 + x^{2}) y^{'} (x) + 4 x y

\frac{3 ( 1 - y ) ^{2}}{2}

\frac{n ( 2 n + 1 ) ( 4 n + 1 )}{3}

(4 x^{2} - y^{2}) d x
