12x2 – 180x + 500 = 0
Dividiendo entre 2
6x^2 - 90x + 250 = 0
Por la fórmula general:
x = [- b +/- (raiz delta)]/2a
delta = b^2 - 4.a.c
= (90)^2 - 4(6)(250)
= 2100
raiz delta = 10(raiz 21)
x = [90 +/- 10(raiz 21)]2x6
x1 = [45 - 5(raiz 21)]/6
x2 = [45 + 5(raiz 21)]/6
S = {[45 - 5(raiz 21)]/6, [45 + 5(raiz 21)]/6}
