expand 2(jln(t)+j-k/t)

expand

2 (j ln (t) + j - \frac{k}{t})

2 j ln (t) + 2 j - \frac{2 k}{t}

Solution steps

2 (j ln (t) + j - \frac{k}{t})

Distribute parentheses

= 2 j ln (t) + 2 j + 2 (- \frac{k}{t})

Apply minus-plus rules

+ (- a) = - a

= 2 j ln (t) + 2 j - 2 \cdot \frac{k}{t}

Multiply

2 \cdot \frac{k}{t} : \frac{2 k}{t}

= 2 j ln (t) + 2 j - \frac{2 k}{t}

8 1^{u (7 p + 7 q)}

(1 - tan (x))^{5}

(y sin (x) + x sin (y)) d x + n (x, y) d y

\frac{2 x ^{2} cos ( x ) - x sin ( x ) ( x ^{2} + 1 )}{x ^{2} + 1}

5 x + 3 y - 4 x y - 7 x + 9 y + 2 x y
