There are a lot of equations in Algebra. We must practice the following Algebra Equations:
» (a+b+c)2=a2+b2+c2+2ab+2bc+2ca
» a2-b2=(a+b)(a-b)
» (a+b)2=(a-b)2+4ab
» (a-b)2=(a+b)2-4ab
» ab={(a+b)2-(a-b)2}/4
» 2(a2+b2)=(a+b)2+(a-b)2
» (a2+b2)={(a+b)2+(a-b)2}/2
» (a+b)3=a3+3a2b+3ab2+b3
» (a-b)3=a3-3a2b+3ab2-b3
» (a+b)3=a3+b3+3ab(a+b)
» (a-b)3=a3-b3-3ab(a-b)
» a3+b3=(a+b)(a2-ab+b2)
» a3-b3=(a-b)(a2+ab-b2)
» a3+b3=(a-b)3+3ab(a-b)
» a3-b3=(a+b)3-3ab(a+b)
» (a+b+c)3=a3+b3+c3+3(a-b)(b-c)(c-a)
» a3+b3+c3-3abc=(a+b+c)(a2+b2+c2-ab-bc-ca)
» a3+b3+c3-3abc=[(a+b+c){(a-b)2+(b-c)2+(c-a)2}]/2
» (x+a)(x+b)=x2+(a+b)x+ab
» (x+a)(x+b)(x+c)=x3+(a+b+c)x2+(ab+bc+ca)x+abc
