expand ((x-4)(349-17x))/7

expand

\frac{( x - 4 ) ( 349 - 17 x )}{7}

- \frac{17 x ^{2}}{7} + \frac{417 x}{7} - \frac{1396}{7}

Solution steps

\frac{( x - 4 ) ( 349 - 17 x )}{7}

Expand

(x - 4) (349 - 17 x) : - 17 x^{2} + 417 x - 1396

= \frac{- 17 x ^{2} + 417 x - 1396}{7}

Apply the fraction rule:

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

\frac{- 17 x ^{2} + 417 x - 1396}{7} = - \frac{17 x ^{2}}{7} + \frac{417 x}{7} - \frac{1396}{7}

= - \frac{17 x ^{2}}{7} + \frac{417 x}{7} - \frac{1396}{7}

\frac{8 y ( r ^{2} - 2 x ^{2} - y ^{2} )}{( r ^{2} - x ^{2} - y ^{2} ) ^{\frac{1}{2}}}

(M = 3, a - 2 b - 7 c) x (N = 10 a - 14 b + 7 c)

\frac{y ^{3} + 2 y ^{2} - 1}{y} d y

\frac{d}{d z} ((f (z)) (z^{2} + 5))

(x + h)^{3} + 1 - x^{3} + 1
