[−b^→ ×(x^→ ×a^→ )]×x^→ =c^→ x^→ ×[b^→ ×(x^→ ×a^→ )]=c^→ x^→ ×[(b^→ .a^→ )x^→ −(b^→ .x^→ )a^→ ]=c^→

x^→ ×(b^→ ∙a^→ )x^→ −(b^→ .x^→ )(x^→ ×a^→ )=−(b^→ ∙x^→ )(x^→ ×a^→ )

−(b^→ ∙x^→ )(x^→ ×a^→ )∙a^→ =0=c^→ ∙a^→ −(b^→ ∙x^→ )(x^→ ×a^→ )∙x^→ =0=c^→ ∙x^→

x^→ =λ_1 a^→ +λ_2 (a^→ ×c^→ ) for some λ_1 ,λ_2 ∈R
