What is expand (1-u-v,1-u,u)*(1,1,1) ?

The solution to expand (1-u-v,1-u,u)*(1,1,1) is 1*(1*1*1,,)-(1*1*1,,)u-(1*1*1,,)v,1-(1*1*1,,)u,u

expand (1-u-v,1-u,u)*(1,1,1)

expand

(1 - u - v, 1 - u, u) \cdot (1, 1, 1)

1 \cdot (1 \cdot 1 \cdot 1,,) - (1 \cdot 1 \cdot 1,,) u - (1 \cdot 1 \cdot 1,,) v, 1 - (1 \cdot 1 \cdot 1,,) u, u

Solution steps

(1 - u - v, 1 - u, u) (1, 1, 1)

= (1 \cdot 1 \cdot 1,,) (1 - u - 1, v -, uu)

Distribute parentheses

= (1, 1, 1) \cdot 1 + (1, 1, 1) (- u) + (1, 1, 1) (- v, 1) + (1, 1, 1) (- u, u)

Apply minus-plus rules

+ (- a) = - a

= 1 \cdot (1 \cdot 1 \cdot 1,,) - (1 \cdot 1 \cdot 1,,) u - (1 \cdot 1 \cdot 1,,) v, 1 - (1 \cdot 1 \cdot 1,,) u, u

(r^{2} - 4 r - 5) \cdot e^{r x}

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

(x - z)^{6}

\frac{1}{2 ( x + 5 ) ( x - 2 )}

\frac{9 n x ^{2} ( n - 1 )}{2}
