En resumen
A) 72X - 14 - 48X - 12 = 24X - 3 72X - 48X - 24X = 14 + 12 - 3 0X = 23 NO TIENE SOLUCION B) 15X + 20 - 15X - 12 = 30 + 45X - 1 15X - 15X - 45X = - 20 + 12 + 30 - 1 - 45X = 21 X = - 21 / 45.
A) 72X - 14 - 48X - 12 = 24X - 3 72X - 48X - 24X = 14 + 12 - 3 0X = 23 NO TIENE SOLUCION
B) 15X + 20 - 15X - 12 = 30 + 45X - 1 15X - 15X - 45X = - 20 + 12 + 30 - 1 - 45X = 21 X = - 21 / 45.
X * = x al cuadrado formula x * - (suma de raizes)x + (multiplicacion de raizes) entonces : x * - ( - 3 - 2)x + ( - 3)( - 2) x * - ( - 5)x + 6 entonces la ecuacion es : x * + 5x + 6.
