Question

qual o resultado?
2x²-24x+6=0

Answer 1

Resposta:

x'= 6-$\sqrt{33}$

x'' = 6+$\sqrt{33}$

Explicação passo-a-passo:

formulas: ax²+bx+c=0

x=$\frac{-b+-\sqrt{b^{2}-4ac } }{2a}$

2x²-24x+6=0

x²-12x+3=0

x= $\frac{-(-12)+-\sqrt{(-12)^{2}-4.1.3 } }{2.1}$

x= $\frac{-(-12)+-\sqrt{(-12)^{2} - 4.3 } }{2}$

x= $\frac{12+-\sqrt{144-12} }{2}$

x= $\frac{12+-2\sqrt{33} }{2}$

x'= 6-$\sqrt{33}$

x''= 6+$\sqrt{33}$
