expand-2left(x+1/7)

expand

- 2 l e f t (x + \frac{1}{7})

- 2 e l f t x - \frac{2 e l f t}{7}

Solution steps

- 2 l e f t (x + \frac{1}{7})

= - 2 e l f t (x + \frac{1}{7})

Apply the distributive law:

a (b + c) = ab + a c

a = - 2 l e f t, b = x, c = \frac{1}{7}

= - 2 l e f t x + (- 2 l e f t) \frac{1}{7}

Apply minus-plus rules

+ (- a) = - a

= - 2 e l f t x - 2 e \frac{1}{7} l f t

2 e \frac{1}{7} l f t = \frac{2 e l f t}{7}

= - 2 e l f t x - \frac{2 e l f t}{7}

\frac{1 - e ^{- s}}{( s ^{2} + 2 s + 17 ) ( s )}

\frac{( 6 - 2 x ) ^{2}}{9}

(a - 1) (b - 1) (c - 1) (b - a) (c - a) (c - b)

\frac{2 ( 2 - 3 ) + 10}{4}

(- - y + 1 + 3)^{2}
