expand (3i,-1j,-1k)*(2i,j,2k)

expand

(3 i, - 1 j, - 1 k) \cdot (2 i, j, 2 k)

3 i (2 \cdot 2 i,, jk), - 1 \cdot j (2 \cdot 2 i,, jk), - 1 \cdot k (2 \cdot 2 i,, jk)

Solution steps

(3 i, - 1 \cdot j, - 1 \cdot k) (2 i, j, 2 k)

= (3 i, - 1, j - 1 \cdot k) (2 \cdot 2 i,, jk)

Distribute parentheses

= (2 i, j, 2 k) \cdot 3 i, (2 i, j, 2 k) (- 1 \cdot j,) + (2 i, j, 2 k) (- 1 \cdot k)

Apply minus-plus rules

+ (- a) = - a

= 3 i (2 \cdot 2 i,, jk), - 1 \cdot j (2 \cdot 2 i,, jk), - 1 \cdot k (2 \cdot 2 i,, jk)

[(x^{2} + 2) (x - 1)]^{^{'}}

\frac{3 ( x + h ) + 7}{7 ( x + h ) - 8}

\frac{3 ( 7 - 2 3 )}{37}

(x + 1) ln (x) (1, e)

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