Alguém sabe resolver equações de 2º grau?

B² - 4.a. C? = (-5)² - 4.4.(-6)?

= 25 + 96? = 121 x = -b±? /2a x = -(-5) ±?121/2.4 x = (5 ± 11)/8 x1 = (5+11)/8 = 16/8 = 2 x2 = (5-11)/8 = -6/8 = -3/4 Sorte!

Não esquece de classificar. Grato... xD.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
