Given a general quadratic equation of the form ax²bxc=0 with x representing an unknown, a, b and c representing constants with a ≠ 0, the quadratic formula is where the plusminus symbol "±" indicates that the quadratic equation has two solutions PolynomialTo find the formula of (a b) 3, we will just multiply (a b) (a b) (a b) (a b) 3 = (a b) (a b) (a b) = (a 2 2ab b 2 ) (a b) = a 3 a 2 b 2a 2 b 2ab 2 ab 2 b 3 = a 3 3a 2 b 3ab 2 b 3 = a 3 3ab (ab) b 3Formulele inmultirii prescurtate Puteri Formulele inmultirii prescurtate Puteri 1 (a 2b)2=a2abb2 2 a2b2= (ab)(a b) 3 (a 3b)3=a3a2b 3ab2b3=a3b33ab(a b) What Is The Formula Of Math A B 3 Math Quora (a+b)^3 formula derivation
