expand-(x(3x-4))/2

Solution

expand

- \frac{x ( 3 x - 4 )}{2}

Solution

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

Solution steps

- \frac{x ( 3 x - 4 )}{2}

Expand

x (3 x - 4) : 3 x^{2} - 4 x

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

Apply the fraction rule:

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

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

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

Remove parentheses:

(a) = a, - (- a) = a

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

Divide the numbers:

\frac{4}{2} = 2

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