Maths formulas (a+b)² =a²+2ab+b² (a-b)² =a²-2ab+b² (a-b)² = (a+b)²-4ab (a+b)² + (a-b)² =2(a²+b²) (a+b)² – (a-b)² = 4ab (a+b)³ = a³+3a²b+3ab²+b³ (a+b)² – (a-b)² = a³+b³+3ab(a+b) (a-b)³ =a³-3a²b+3ab²-b³ (a-b)³ =a³+b³+3ab(a+b) (a+b)³ + (a-b)³ = 2(a³+3ab²) (a+b)³ + (a-b)³ =2a(a²+3b²) (a+b)³ – (a-b)³ =3a²b+2b³ (a+b)³ – (a-b)³ =2b(3a²+b²) a²-b² =(a-b)(a+b) a³+b³ = (a+b)(a²-ab+b²) a³-b³ = (a-b)(a²+ab+b²) a³-b³ = (a-b)³ + 3ab(a-b) (a+b+c)² = a²+b²+c²+2(ab+bc+ca) (a+b+c)³ =a³+b³+c³+3(a+b)(b+c)(c+a) a³+b³+c³ =(a+b+c)³ – 3(a+b)(b+c)(c+a) *(a+b+c+d)² =* a²+b²+c²+d²+2(ab+ac+ad+bc+bd+cd) *a³+b³+c³-3abc =* (a+b+c)(a²+b²+c²-ab-bc-ca)।
