expand ((x+20)(x+87))/2

expand

\frac{( x + 20 ) ( x + 87 )}{2}

\frac{x ^{2}}{2} + \frac{107 x}{2} + 870

Solution steps

\frac{( x + 20 ) ( x + 87 )}{2}

Expand

(x + 20) (x + 87) : x^{2} + 107 x + 1740

= \frac{x ^{2} + 107 x + 1740}{2}

Apply the fraction rule:

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

\frac{x ^{2} + 107 x + 1740}{2} = \frac{x ^{2}}{2} + \frac{107 x}{2} + \frac{1740}{2}

= \frac{x ^{2}}{2} + \frac{107 x}{2} + \frac{1740}{2}

Divide the numbers:

\frac{1740}{2} = 870

= \frac{x ^{2}}{2} + \frac{107 x}{2} + 870

(x - π) \cdot (y - 2)^{2}

g [f (m + 2)]

\frac{A ( 1 - x ) + B ( x )}{( x ) ( 1 - x )}

cos (3) (t - π)
