expand (5(-10+sqrt(2)))/(98)

expand

\frac{5 ( - 10 + 2 )}{98}

- \frac{25}{49} + \frac{5}{49 2}

Decimal Notation

- 0.43805 \dots

Solution steps

\frac{5 ( - 10 + 2 )}{98}

Expand

5 (- 10 + 2) : - 50 + 52

= \frac{- 50 + 5 2}{98}

Apply the fraction rule:

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

\frac{- 50 + 5 2}{98} = - \frac{50}{98} + \frac{5 2}{98}

= - \frac{50}{98} + \frac{5 2}{98}

\frac{50}{98} = \frac{25}{49}

\frac{5 2}{98} = \frac{5}{49 2}

= - \frac{25}{49} + \frac{5}{49 2}

(6 a + b, 11) (2, 5 a + 2 b)

(3 x + \frac{1}{2}) (3 x - \frac{1}{2})

\frac{( x + 0.01 ) ( 0.5 x + 0.04 ) ^{\frac{1}{2}}}{4 - x}

\frac{d}{d t} ((x) (2 x + 3 y))

\frac{100 x}{( x ^{2} + 25 ) ^{2}}
