Question

Qual a delta e bhaskara de 2x²-12x=0?

Answer 1

2x² - 12x = 0 

a = 2
b = -12
c = 0

Δ = b² - 4×a×c

Δ = -12² - 4 ×2 × 0

Δ = 144 - 0

Δ = 144

BHASKARA

-b +/- √Δ
-------------
     2a



12 +/- √144
---------------
       2×2


12 +/- 12
------------
     4


x'= 12 + 12
  --------------
          4

x' = 6


x'' = 12 - 12
       ----------
             4

x'' = 0 


Respostas:
x' = 6   x''= 0
