expand (-4x,-1,2y+1)*(0,2,1)

expand

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

- 4 (0 \cdot 2 \cdot 1,,) x, - 1 \cdot (0 \cdot 2 \cdot 1,,), 2 y + 1 \cdot (0 \cdot 2 \cdot 1,,)

Solution steps

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

= (0 \cdot 2 \cdot 1,,) (- 4, x - 1 \cdot 2, y + 1)

Distribute parentheses

= (0, 2, 1) (- 4 x,) + (0, 2, 1) (- 1, 2 y) + (0, 2, 1) \cdot 1

Apply minus-plus rules

+ (- a) = - a

= - 4 (0 \cdot 2 \cdot 1,,) x, - 1 \cdot (0 \cdot 2 \cdot 1,,), 2 y + 1 \cdot (0 \cdot 2 \cdot 1,,)

e^{x y} (y + x \frac{d y}{d x})

\frac{9 \cdot 2}{n} - (\frac{n ( n + 1 ) ( 2 n + 1 )}{6}) (\frac{2}{n})^{3}

lo g_{10} (10) (x) - lo g_{10} (10) (x)

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

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