expand 1/3 (a)-1/3 (b)

expand

\frac{1}{3} (a) - \frac{1}{3} (b)

\frac{a}{3} - \frac{b}{3}

Solution steps

\frac{1}{3} (a) - \frac{1}{3} (b)

Remove parentheses:

(a) = a

= \frac{1}{3} a - \frac{1}{3} b

\frac{1}{3} a = \frac{a}{3}

\frac{1}{3} b = \frac{b}{3}

= \frac{a}{3} - \frac{b}{3}

Apply rule

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{a - b}{3}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{a - b}{3} = \frac{a}{3} - \frac{b}{3}

= \frac{a}{3} - \frac{b}{3}

(x + h) ∣ x + h ∣ - x ∣ x ∣

\frac{\partial}{\partial x} ((z) (e^{7 z} - x yz))

cos ((1 - t^{6}) \cdot (t^{4} - 2 t)^{2})

(2 x + 5) e^{(x)}

\frac{( p x ^{2} + r + b x ) ( - k - m x ^{2} - b x - r )}{r + b x}
