Question

(x-2).(2x^​+3).(5-3x)=0                                        Giải cả bài giúp mình nhé!đúng = tick

 

Answer 1

(x-2).(2x^​+3).(5-3x)=0

=> x - 2 = 0 => x = 2

   2x + 3 = 0 => 2x = -3 => x = -1,5

   5 - 3x = 0 => 3x = 5 => x = \(\frac{5}{3}\)

Answer 2

(x-2).(2x^​+3).(5-3x)=0

TH1:

x-2 =0 => x=2

TH2:

2x +3 = 0 => 2x =-3  => x= -3/2 

TH3:

5-3x =0  =>  3x= 5 => x= 5/3

Vậy x=2; -3/2 ; 5/3

Answer 3

(x-2).(2x^​+3).(5-3x)=0

\(\Rightarrow\hept{\begin{cases}x-2=0\\2x+3=0\\5-3x=0\end{cases}\Rightarrow\hept{\begin{cases}x=2\\2x=3\\3x=5\end{cases}\Rightarrow}\hept{\begin{cases}x=2\\x=\frac{3}{2}\\x=\frac{5}{3}\end{cases}}}\)

Vậy \(x=2;\frac{3}{2};\frac{5}{3}\)
