simplify 12(m-1/2)

Solution

simplify

12 (m - \frac{1}{2})

12 m - 6

Solution steps

12 (m - \frac{1}{2})

Join

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

= 12 \cdot \frac{m \cdot 2 - 1}{2}

= 12 \cdot \frac{2 m - 1}{2}

Apply the fraction rule:

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

= \frac{12 ( 2 m - 1 )}{2}

Divide the numbers:

\frac{12}{2} = 6

= 6 (2 m - 1)

Expand

6 (2 m - 1) : 12 m - 6

= 12 m - 6

(4 x - 8 y) (4 x + 8 y)

(2 x e^{x} - 2 e^{x})^{2}
