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
