expand (a+b+c+d+e)^2

expand

(a + b + c + d + e)^{2}

2 e a + 2 ab + 2 a c + 2 a d + a^{2} + e^{2} + b^{2} + 2 e b + 2 b c + c^{2} + 2 ec + 2 b d + 2 c d + d^{2} + 2 e d

Solution steps

(a + b + c + d + e)^{2}

(a + b + c + d + e)^{2} = (a + b + c + d + e) (a + b + c + d + e)

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

Expand

(a + b + c + d + e) (a + b + c + d + e) : 2 e a + 2 ab + 2 a c + 2 a d + a^{2} + e^{2} + b^{2} + 2 e b + 2 b c + c^{2} + 2 ec + 2 b d + 2 c d + d^{2} + 2 e d

= 2 e a + 2 ab + 2 a c + 2 a d + a^{2} + e^{2} + b^{2} + 2 e b + 2 b c + c^{2} + 2 ec + 2 b d + 2 c d + d^{2} + 2 e d

(- 3 + 3) + (- 33 - 1) i

\frac{3 ( - x + 1 )}{4 ( x - 2 ) ^{2}}

\frac{15 π ( 17 - 5 )}{4}

\frac{s ^{3} + s x ^{2} + s + 5}{( s ^{2} + 1 ) ( s ^{2} + 4 s + 8 )}
