expand (1,-2,0)X(2,1,0)

expand

(1, - 2, 0) X (2, 1, 0)

1 \cdot (2 \cdot 1 \cdot 0,,) X, - 2 (2 \cdot 1 \cdot 0,,) X, 0

Solution steps

(1, - 2, 0) X (2, 1, 0)

= (1, - 2 \cdot 0,) (2 \cdot 1 \cdot 0,,) X

Apply the distributive law:

a (b - c) = ab - a c

a = X (2, 1, 0), b = 1,, c = 2, 0

= X (2, 1, 0) \cdot 1, - X (2, 1, 0) \cdot 2, 0

= 1 \cdot (2 \cdot 1 \cdot 0,,) X, - 2 (2 \cdot 1 \cdot 0,,) X, 0

[- (x - 6)]^{2}

\frac{k}{s ( s ^{2} + 9 s + 9 )}

(x^{3} - 6) \circ (3 x + 2)

(- 2, - 3) y (3, 2)

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