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

expand

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

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

Solution steps

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

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

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

Expand

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

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

(\cdot + 2) (y + 3)

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

π (- 2 sin (π y) + π cos (π y))

\frac{- 1}{3} (2 y - 9 = - 2)

(1 + y + y^{2}) d x + x (x^{2} - 4) d y
