expand ((X+40)(X+82))/2

expand

\frac{( X + 40 ) ( X + 82 )}{2}

\frac{X ^{2}}{2} + 61 X + 1640

Solution steps

\frac{( X + 40 ) ( X + 82 )}{2}

Expand

(X + 40) (X + 82) : X^{2} + 122 X + 3280

= \frac{X ^{2} + 122 X + 3280}{2}

Apply the fraction rule:

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

\frac{X ^{2} + 122 X + 3280}{2} = \frac{X ^{2}}{2} + \frac{122 X}{2} + \frac{3280}{2}

= \frac{X ^{2}}{2} + \frac{122 X}{2} + \frac{3280}{2}

Divide the numbers:

\frac{122}{2} = 61

= \frac{X ^{2}}{2} + 61 X + \frac{3280}{2}

Divide the numbers:

\frac{3280}{2} = 1640

= \frac{X ^{2}}{2} + 61 X + 1640

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

\frac{5 ^{22}}{5 ^{22}}

e^{- k} (1 - a) - e^{- 2 k} (1 - a)

\frac{1}{( x + 2 ) ^{2} ( 3 x + 6 )}

- \frac{3 y ^{2} ( - 3 y + 3 ) ^{2}}{2}
