expand (bi+cj+dk)^2

expand

(bi + c j + d k)^{2}

i^{2} b^{2} + 2 ijb c + 2 ib d k + j^{2} c^{2} + 2 j c d k + d k^{2}

Solution steps

(bi + c j + d k)^{2}

= (ib + j c + d k)^{2}

(bi + c j + d k)^{2} = (bi + c j + d k) (bi + c j + d k)

= (ib + j c + d k) (ib + j c + d k)

Expand

(bi + c j + d k) (bi + c j + d k) : i^{2} b^{2} + 2 ijb c + 2 ib d k + j^{2} c^{2} + 2 j c d k + d k^{2}

= i^{2} b^{2} + 2 ijb c + 2 ib d k + j^{2} c^{2} + 2 j c d k + d k^{2}

(1 + e^{x}) d x

\frac{- 6 x ^{2} - 43 x + 103}{( x + 5 ) ( x + 2 ) ( x + 13 )}

(x^{2} - 2 x y + y^{2} = 3) (- 1)

\frac{60 ( s + 6 )}{s ^{3} + 9 s + 168}

\frac{1}{( 5 x + 2 ) ^{2}}
