expand (-y,z-1,-1)*(1,1,1)

expand

(- y, z - 1, - 1) \cdot (1, 1, 1)

- (1 \cdot 1 \cdot 1,,) y, z - 1 \cdot (1 \cdot 1 \cdot 1,,), - 1 \cdot (1 \cdot 1 \cdot 1,,)

Solution steps

(- y, z - 1, - 1) (1, 1, 1)

= (1 \cdot 1 \cdot 1,,) (-, yz - 1, - 1)

Distribute parentheses

= (1, 1, 1) (- y, z) + (1, 1, 1) (- 1,) + (1, 1, 1) (- 1)

Apply minus-plus rules

+ (- a) = - a

= - (1 \cdot 1 \cdot 1,,) y, z - 1 \cdot (1 \cdot 1 \cdot 1,,), - 1 \cdot (1 \cdot 1 \cdot 1,,)

\frac{1}{3 - 1} - sin (3 - 1)

\frac{2 ( cos ( \frac{πn}{2} ) - 1 )}{π ^{2} n ^{2}}

\frac{17 ( P + Ds )}{34 s ^{2} + 17 s + 0.6}

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

(\frac{x}{- 0.08})^{2}
