expand a(b+c+d+e)+b(c+d+e)+c(d+e)+de

expand

a \cdot (b + c + d + e) + b \cdot (c + d + e) + c \cdot (d + e) + d \cdot e

ab + a c + a d + e a + b c + b d + e b + c d + ec + d e

Solution steps

a (b + c + d + e) + b (c + d + e) + c (d + e) + d e

= a (b + c + d + e) + b (c + d + e) + c (d + e) + e d

Expand

a (b + c + d + e) : ab + a c + a d + e a

= ab + a c + a d + e a + b (c + d + e) + c (d + e) + d e

Expand

b (c + d + e) : b c + b d + e b

= ab + a c + a d + e a + b c + b d + e b + c (d + e) + d e

Expand

c (d + e) : c d + ec

= ab + a c + a d + e a + b c + b d + e b + c d + ec + d e

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

\frac{x + 5}{( x + 2 ) ^{2}}

4 (\frac{x}{3} + 6 = 40)

\frac{1}{2 ( ( 2 x - 3 ) ^{3} )}

(m_{1} \cdot m_{2}) x^{''} + k (x - l) (m_{1} - m_{2})
