Question

Tìm x:

(4.x+3)³.(\(\frac{3}{2}\)+2.x)²=0

Giúp mình với nhé. Cảm ơn!!

Answer 1

(4x + 3)³.(\(\frac{3}{2}\)+ 2x)² = 0

\(\Rightarrow\left[{}\begin{matrix}\left(4x+3\right)^3=0\\\left(\frac{3}{2}+2x\right)^2=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}4x+3=0\\\frac{3}{2}+2x=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=\frac{-3}{4}\\x=\frac{-3}{4}\end{matrix}\right.\)

Vậy x = \(\frac{-3}{4}\)
