expand 2*(x-3,y-4)

expand

2 \cdot (x - 3, y - 4)

2 x - 2 \cdot 3, y - 2 \cdot 4

Solution steps

2 (x - 3, y - 4)

Distribute parentheses

= 2 x + 2 (- 3, y) + 2 (- 4)

Apply minus-plus rules

+ (- a) = - a

= 2 x - 2 \cdot 3, y - 2 \cdot 4

(e^{7 x} - e^{- 7 x})^{2}

\frac{1}{( s - 2 ) ( s - 4 )}

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

\frac{2}{s ( s + 1 )}

\frac{n ^{2} ( n + 1 ) ^{2} + 4 ( n + 1 ) ^{3}}{4}
