expand 2pix-(2pi(-2pix+10))/9

expand

2 π x - \frac{2 π ( - 2 π x + 10 )}{9}

2 π x + \frac{4 π ^{2} x}{9} - \frac{20 π}{9}

Solution steps

2 π x - \frac{2 π ( - 2 π x + 10 )}{9}

Expand

2 π (- 2 π x + 10) : - 4 π^{2} x + 20 π

= 2 π x - \frac{- 4 π ^{2} x + 20 π}{9}

Apply the fraction rule:

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

\frac{- 4 π ^{2} x + 20 π}{9} = - (- \frac{4 π ^{2} x}{9}) - (\frac{20 π}{9})

= 2 π x - (- \frac{4 π ^{2} x}{9}) - (\frac{20 π}{9})

Remove parentheses:

(a) = a, - (- a) = a

= 2 π x + \frac{4 π ^{2} x}{9} - \frac{20 π}{9}

\frac{2}{x ( x + h )}

(x^{2} - 1) p^{'} (x) n

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

A (3, 4) B (3, - 5)

\frac{3 ( b + a )}{4}
