Question

6x^2+60x+150=0 calcule o x

Answer 1

6x^2+60x+150=0 ===> :(6)

x² +10x + 25 = 0

(x+5)² = 0

x+5 = 0

x = -5 ✓

Answer 2

Equação do 2° Grau!

6x² + 60x + 150 = 0

Coeficientes:

A= 6
B= 60
C= 150

∆= b² - 4ac

∆= 60² - 4 • 6 • 150
∆= 3600 - 3600
∆= 0

x= - b ± √∆/2a

x= - 60 ± √0 / 2 • 6
x= - 60 ± 0 / 12

x'= - 60 + 0 / 12 = - 60/12 = - 5
x"= - 60 - 0/12= - 60/12 = - 5

S= ( - 5)
