Question

Quais sao as raizes desta equaçao x² - 5x + 6 = 0 ?

Answer 1

$Equacao:x^{2}-5x+6=0\\\\a=1\\b=-5\\c=6\\Utilizando\ a\ formula\ de\ Bhaskara:\\\\\Delta=b^{2}-4.a.6\\\Delta=-5^{2}-4.1.6\\\Delta=25-24\\\Delta=1\\\\X=\begin{cases} & \text{ x' }=\frac{-(-5)+\sqrt{1} }{2}=\frac{4}{2} = 2 \\\\ & \text x"= \frac{-(-5)-\sqrt{1} }{2}=\frac{6}{2} = 3 \\\end{cases}\\\\Portanto\ a\ resposta\ e : (3,2)$
