expand (-2,-1,2)x(2,2,2)

expand

(- 2, - 1, 2) x (2, 2, 2)

- 2 (2 \cdot 2 \cdot 2,,) x, - 1 \cdot (2 \cdot 2 \cdot 2,,) x, 2

Solution steps

(- 2, - 1, 2) x (2, 2, 2)

= (- 2, - 1 \cdot 2,) (2 \cdot 2 \cdot 2,,) x

Apply the distributive law:

a (b - c) = ab - a c

a = x (2, 2, 2), b = - 2,, c = 1, 2

= x (2, 2, 2) (- 2,) - x (2, 2, 2) \cdot 1, 2

Apply minus-plus rules

+ (- a) = - a

= - 2 (2 \cdot 2 \cdot 2,,) x, - 1 \cdot (2 \cdot 2 \cdot 2,,) x, 2

(x_{+ 1})^{2}

(sin (θ) - e^{- i x} cos (θ))^{2}

(x (x^{2} + 1)^{3}) d x

y (2 x - y e^{y})

\frac{( x - 6 ) ^{2}}{( 2 - 3 x )}
