expand (5i,3j,2k)(-4i,-1j,-5k)

expand

(5 i, 3 j, 2 k) (- 4 i, - 1 j, - 5 k)

- 4 i (5 \cdot 3 \cdot 2 i,, jk), - 1 \cdot j (5 \cdot 3 \cdot 2 i,, jk), - 5 k (5 \cdot 3 \cdot 2 i,, jk)

Solution steps

(5 i, 3 j, 2 k) (- 4 i, - 1 \cdot j, - 5 k)

= (5 \cdot 3 \cdot 2 i,, jk) (- 4 i, - 1, j - 5 k)

Distribute parentheses

= (5 i, 3 j, 2 k) (- 4 i,) + (5 i, 3 j, 2 k) (- 1 \cdot j,) + (5 i, 3 j, 2 k) (- 5 k)

Apply minus-plus rules

+ (- a) = - a

= - 4 i (5 \cdot 3 \cdot 2 i,, jk), - 1 \cdot j (5 \cdot 3 \cdot 2 i,, jk), - 5 k (5 \cdot 3 \cdot 2 i,, jk)

\frac{1}{( s + 2 ) ( rcs + 1 )}

\frac{64 x ^{2} - 80 x y + 25 y ^{2}}{( - 10 x + 10 y ) ( - 4 x + y )}

- 1512

(30 \cdot 2) + (4 \cdot 2)

\frac{x + 6}{4 ( x - 3 )}
