expand (2i,3j,-4k)(i-3j+k)

expand

(2 i, 3 j, - 4 k) (i - 3 j + k)

2 i, 3 j, i - 2 i, 3 j, 3 j + 2 i, 3 j, k - 4 ik + 4 \cdot 3 jk - 4 kk

Solution steps

(2 i, 3 j, - 4 k) (i - 3 j + k)

= (2 \cdot 3 i,, j - 4 k) (i - 3 j + k)

Distribute parentheses

= 2 i, 3 j, i + 2 i, 3 j, (- 3 j) + 2 i, 3 j, k + (- 4 k) i + (- 4 k) (- 3 j) + (- 4 k) k

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= 2 i, 3 j, i - 2 i, 3 j, 3 j + 2 i, 3 j, k - 4 ik + 4 \cdot 3 jk - 4 kk

\frac{8 ( 8 - x )}{64 - x}

(- 10 + 11) (- 4 + 10)

\frac{( ( x + y ) ( ( x + y ) + 1 ) - ( x x + 1 ) )}{y}

k + 2 k + 1

\frac{( x + 2 ) ( x - 3 )}{4 ( 3 x - 1 ) ( x + 1 )}
