Question

(4x+3) = (4x +3)(x - 2)

Answer 1

\(\left(4x+3\right)=\left(4x+3\right)\left(x-2\right)\)

\(\Leftrightarrow\left(4x+3\right)-\left(4x+3\right)\left(x-2\right)=0\)

\(\Leftrightarrow\left(4x+3\right)\left(1-x+2\right)=0\)

\(\Leftrightarrow\left(4x+3\right)\left(-x+3\right)=0\)

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

Vậy...
