a: Ta có: \(2x-3=0\)
\(\Leftrightarrow2x=3\)
hay \(x=\dfrac{3}{2}\)
b: Ta có: \(\left(2x+7\right)\left(x-3\right)=0\)
\(\Leftrightarrow\left[{}\begin{matrix}x=-\dfrac{7}{2}\\x=3\end{matrix}\right.\)
c: Ta có: \(2x+7=-3x+32\)
\(\Leftrightarrow5x=25\)
hay x=5
d: Ta có: \(\left(3x-2\right)\left(4x+5\right)=0\)
