a) \(\left(x+2\right)^2=4\left(2x-1\right)^2\)

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

\(\left(x+2\right)^2-\left[2\left(2x-1\right)\right]^2=0\)

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

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

\(6x\left(-3x+4\right)=0\)

\(\Rightarrow6x=0\) hoặc \(-3x+4=0\)

*) \(6x=0\)

\(x=0\)

*) \(-3x+4=0\)

\(3x=4\)

\(x=\dfrac{4}{3}\)

Vậy \(x=0;x=\dfrac{4}{3}\)

b) \(4x\left(x-2019\right)-x+2019=0\)

\(4x\left(x-2019\right)-\left(x-2019\right)=0\)

\(\left(x-2019\right)\left(4x-1\right)=0\)

\(\Rightarrow x-2019=0\) hoặc \(4x-1=0\)

*) \(x-2019=0\)

\(x=2019\)

*) \(4x-1=0\)

\(4x=1\)

\(x=\dfrac{1}{4}\)

Vậy \(x=\dfrac{1}{4};x=2019\)
