\(\dfrac{2}{3}.20\%.\dfrac{10}{7}=\dfrac{2}{3}.\dfrac{20}{100}.\dfrac{10}{7}=\dfrac{2}{3}.\dfrac{1}{5}.\dfrac{10}{7}=\dfrac{4}{21}\)
\(x^2+4x-5=0\) ( a = 1 ; b, = 2 ; c = - 5 )
\(\Delta^,=\left(b^,\right)^2-a.c\)
\(=2^2-1.\left(-5\right)\)
\(=9>0\)
pt có 2 no phân 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
