Algebraic Identity - Square of Trinomial

Let us take a trinomial dpi{100} large (a+b+c)^2

Let                             large a+b= x

Now ,square the trinomial as follows:

large therefore (a+b+c)^{2}= (x+c)^{2}

                                large = large x^{2}+2xc+c^{2}

                                large = (a+b)^{2}+2(a+b)c+c^{2}

                                large = a^{2}+2ab +b^{2}+2ac+2bc+c^{2}

                                 large a^{2}+b^{2}+c^{2}+2ab+2bc +2ca

            large therefore (a+b+c)^{2}= a ^{2}+b^{2}+c^{2}+2ab+2bc+2ca

IllustrationExpand large (3x+2y+7)^{2}
