expand (9(2-sqrt(2)))/2

expand

\frac{9 ( 2 - 2 )}{2}

9 - \frac{9}{2}

Decimal Notation

2.63603 \dots

Solution steps

\frac{9 ( 2 - 2 )}{2}

Expand

9 (2 - 2) : 18 - 92

= \frac{18 - 9 2}{2}

Apply the fraction rule:

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

\frac{18 - 9 2}{2} = \frac{18}{2} - \frac{9 2}{2}

= \frac{18}{2} - \frac{9 2}{2}

Divide the numbers:

\frac{18}{2} = 9

= 9 - \frac{9 2}{2}

Cancel

\frac{9 2}{2} : \frac{9}{2}

= 9 - \frac{9}{2}

(1 + tan (α) tan (β)) tan (α + β)

(- x - 3) (- x + 3)

(a + e - b + i) x^{2} + (a + e + b + i) x + (c + o)

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

\frac{4 x - 5}{( x ^{2} - 2 x + 2 ) ^{\frac{3}{2}}}
