expand x(1,1,1)+y(0,1,-1)+z(0,0,2)

expand

x (1, 1, 1) + y (0, 1, - 1) + z (0, 0, 2)

x (1, 1, 1) + 0 \cdot y, 1, - 1 \cdot y + z (0, 0, 2)

Solution steps

x (1, 1, 1) + y (0, 1, - 1) + z (0, 0, 2)

= (1 \cdot 1 \cdot 1,,) x + (0 \cdot 1,, - 1) y + (0 \cdot 0 \cdot 2,,) z

Expand

y (0, 1, - 1) : 0 \cdot y, 1, - 1 \cdot y

= x (1, 1, 1) + 0 \cdot y, 1, - 1 \cdot y + z (0, 0, 2)

f x (1, - 2)

(e^{t} + a t - 2) (t^{3} - 2 t^{2} + 1)

\frac{5 s ^{2} + 44}{( s ^{2} + 44 ) ( s + 2 )}
