expand (2m+4)-(2(5m+1))/5

expand

(2 m + 4) - \frac{2 ( 5 m + 1 )}{5}

- \frac{2}{5} + 4

Decimal Notation

3.6

Solution steps

(2 m + 4) - \frac{2 ( 5 m + 1 )}{5}

Remove parentheses:

(a) = a

= 2 m + 4 - \frac{2 ( 5 m + 1 )}{5}

Expand

2 (5 m + 1) : 10 m + 2

= 2 m + 4 - \frac{10 m + 2}{5}

Apply the fraction rule:

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

\frac{10 m + 2}{5} = - (\frac{10 m}{5}) - (\frac{2}{5})

= 2 m + 4 - (\frac{10 m}{5}) - (\frac{2}{5})

Remove parentheses:

(a) = a

= 2 m + 4 - \frac{10 m}{5} - \frac{2}{5}

Divide the numbers:

\frac{10}{5} = 2

= 2 m + 4 - 2 m - \frac{2}{5}

Group like terms

= 2 m - 2 m - \frac{2}{5} + 4

Add similar elements:

2 m - 2 m = 0

= - \frac{2}{5} + 4

(sin^{4} (x) + cos^{4} (x) - 1) (sec^{2} (x) + csc^{2} (x))

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

\frac{4 ln ( 2 )}{x ( 4 + ln ( x ) ) ^{2}}
