simplify 15(2/5-3x)

Solution

simplify

15 (\frac{2}{5} - 3 x)

- 45 x + 6

Solution steps

15 (\frac{2}{5} - 3 x)

Join

\frac{2}{5} - 3 x : \frac{- 15 x + 2}{5}

= 15 \cdot \frac{- 15 x + 2}{5}

Apply the fraction rule:

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

= \frac{15 ( - 15 x + 2 )}{5}

Divide the numbers:

\frac{15}{5} = 3

= 3 (- 15 x + 2)

Expand

3 (- 15 x + 2) : - 45 x + 6

= - 45 x + 6

15 (\frac{2}{5} - 3 v)

(x - a + x - a)^{2}

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

(1 - sin (a) - cos (a))^{2}

\frac{5 ( x ^{4} - 1 )}{2}
