simplify 4(x-1/2)

Solution

simplify

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

4 x - 2

Solution steps

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

Join

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

= 4 \cdot \frac{x \cdot 2 - 1}{2}

= 4 \cdot \frac{2 x - 1}{2}

Apply the fraction rule:

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

= \frac{4 ( 2 x - 1 )}{2}

Divide the numbers:

\frac{4}{2} = 2

= 2 (2 x - 1)

Expand

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

= 4 x - 2

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

(- 1 + i 3)^{10}

(3 x + 4 i)^{2}

- 2 (2 + 2 - 2)

\frac{1}{( x + 1 ) ( x + 2 ) ( x + 3 )}
