y la suma de los dos numeros es 50
(2x)(2x+2)=624 --->
(x)(x+1)=156
x^2 +x = 156 -- x^2 +x - 156=0
aplicando la formula de la ecuacion cuadratica obtienes x1=12; x2=-13
para x1=12 --> 2x=24 ; 2x+2=26
(2*12)(2*12 + 2)=624 (2*12)+(2*12 + 2)=50
para x2=-13 ---> 2x=-26 ; 2x+2=-24
(2*(-13))(2*(-13) + 2)=624 (2*(-13))+(2*(-13) + 2) =-50
