expand ((6x-1)(x+4))/2

expand

\frac{( 6 x - 1 ) ( x + 4 )}{2}

3 x^{2} + \frac{23 x}{2} - 2

Solution steps

\frac{( 6 x - 1 ) ( x + 4 )}{2}

Expand

(6 x - 1) (x + 4) : 6 x^{2} + 23 x - 4

= \frac{6 x ^{2} + 23 x - 4}{2}

Apply the fraction rule:

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

\frac{6 x ^{2} + 23 x - 4}{2} = \frac{6 x ^{2}}{2} + \frac{23 x}{2} - \frac{4}{2}

= \frac{6 x ^{2}}{2} + \frac{23 x}{2} - \frac{4}{2}

Divide the numbers:

\frac{6}{2} = 3

= 3 x^{2} + \frac{23 x}{2} - \frac{4}{2}

Divide the numbers:

\frac{4}{2} = 2

= 3 x^{2} + \frac{23 x}{2} - 2

(3 x^{2} - 10 x + 14) d x

(1 - 0.8 e^{- i x})^{2}

2 (2 e^{\frac{x}{2}} + C)

\frac{2}{( 1 + e ^{- 8 (x - 0.7)} )} - 1
