                      being sick , I couldn't go out .

                      my sickness , I couldn't go out .

\(\dfrac{2}{3}.20\%.\dfrac{10}{7}=\dfrac{2}{3}.\dfrac{20}{100}.\dfrac{10}{7}=\dfrac{2}{3}.\dfrac{1}{5}.\dfrac{10}{7}=\dfrac{4}{21}\)

\(x^2+4x-5=0\)  ( a = 1 ; b, = 2 ; c = - 5 ) 

\(\Delta^,=\left(b^,\right)^2-a.c\)

      \(=2^2-1.\left(-5\right)\)

      \(=9>0\)

pt có 2 nphân biệt :

\(x_1=\dfrac{-b^,+\sqrt{\Delta}}{a}=1\)

\(x_2=\dfrac{-b^,-\sqrt{\Delta}}{a}=-5\)

Vậy pt có no : x = 1

                      x = - 5
