Question

Resolva a Equaçao x²-5x+6=0

Answer 1

$x^2-5x+6=0 \\ \\ a = 1 \\ b=-5 \\ c=6 \\ \\ Delta = b^2-4*a*c \\Delta=(-5)^2-4*1*6 \\ Delta = 25 - 24 \\ Delta= 1 \\ \\ X= \frac{-b \frac{+}{} \sqrt{Delta} }{2*a} \\ \\X= \frac{-(-5) \frac{+}{} \sqrt{1} }{2*1} \\ \\ X'= \frac{5+1}{2}= \frac{6}{2}=3 \\ \\ X''= \frac{5-1}{2}= \frac{4}{2}=2 \\ \\ \\ S={3,2} \\ \\ -Espero~Ter~Ajudado~E~Bons~Estudos~!!$
