Question

Como resuelvo esta ecuación de segundo grado
x+x2=182

Answer 1

resolver.

x + x² = 182
x² + x - 182 = 0

formula.

a = 1
b= 1
c = - 182

x = [ -b ±√(b² - 4ac)]/2a

x = [ - 1± √(1² -4(1)(-182))]/2(1)

x = [ -1 ± √( 1 +728)]/2
x = [ -1 ± √729]/2
x = [ - 1 ± 27]/2
x1 = (- 1 + 27)/2
x1 = 26/2
x = 13
  o
x2 = (-1 - 27)/2
x = - 28/2
x = - 14

Solucion.
(13 , - 14)
