Solution steps

(2 + 2) \cdot 4

= 4 (2 + 2)

Apply the distributive law:

a (b + c) = ab + a c

4 (2 + 2) = 4 \cdot 2 + 42

= 4 \cdot 2 + 42

Multiply the numbers:

4 \cdot 2 = 8

= 8 + 42

\frac{\frac{d}{d x} ( 2 x + 1 )}{( x + 1 ) ^{2}}

\frac{1}{( s ^{2} + 2 s + 2 )} (\frac{1}{( s + 1 ) ^{2}})

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

\frac{n ^{2} ( n + 1 ) ^{2}}{4} + (n + 1)

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