simplify 8(-x-1/2)

Solution

simplify

8 (- x - \frac{1}{2})

- 8 x - 4

Solution steps

8 (- x - \frac{1}{2})

Join

- x - \frac{1}{2} : \frac{- x \cdot 2 - 1}{2}

= 8 \cdot \frac{- x \cdot 2 - 1}{2}

= 8 \cdot \frac{- 2 x - 1}{2}

Apply the fraction rule:

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

= \frac{8 ( - 2 x - 1 )}{2}

Divide the numbers:

\frac{8}{2} = 4

= 4 (- 2 x - 1)

Expand

4 (- 2 x - 1) : - 8 x - 4

= - 8 x - 4

a (cos (Θ) + Θ sin (Θ))

\frac{( x - 2 ) ^{3}}{x}

(7 + cos (θ))^{2}

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

(1 - \frac{3}{3}) (1 + \frac{3}{3})
