Identidades polinómicas
(Mathemática | Álgebra | Polinómicas)

(a+b) 2 = a2 + 2ab + b2

(a+b)(c+d) = ac + ad + bc + bd

a2 - b2 = (a+b)(a-b) (La diferencia de cuadrados)

a3 (+-) b3 = (a (+-) b)(a2 (-+) ab + b2) (La suma y la diferencia de cubos)

x2 + (a+b)x + ab = (x + a)(x + b)

Si ax2 + bx + c = 0 entonces x = ( -b (+-)sqrt(b2 - 4ac) ) / 2a (la fórmula cuadrática)
