expand ((x+3)(x+6))/2

expand

\frac{( x + 3 ) ( x + 6 )}{2}

\frac{x ^{2}}{2} + \frac{9 x}{2} + 9

Solution steps

\frac{( x + 3 ) ( x + 6 )}{2}

Expand

(x + 3) (x + 6) : x^{2} + 9 x + 18

= \frac{x ^{2} + 9 x + 18}{2}

Apply the fraction rule:

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

\frac{x ^{2} + 9 x + 18}{2} = \frac{x ^{2}}{2} + \frac{9 x}{2} + \frac{18}{2}

= \frac{x ^{2}}{2} + \frac{9 x}{2} + \frac{18}{2}

Divide the numbers:

\frac{18}{2} = 9

= \frac{x ^{2}}{2} + \frac{9 x}{2} + 9

(1, - 2) (x, y)

(2) (4 x + 3 y = 9)

(58)^{3}

\frac{3 ( 10000 π ^{2} + 16 )}{16}

(2 x - 1) (e^{x} x - e^{x} + c)
