Answer 2

$\Large\mathsf\displaystyle{}\left(2x - 1\right)^{2} \\ \Large\mathsf\displaystyle{}\left(2x\right)^{2} - 2\cdot2x\cdot1 + {1}^{2} \\ \Large\mathsf\displaystyle{} {4x}^{2} - 2\cdot2x\cdot1 + {1}^{2} \\ \Large\mathsf\displaystyle{} {4x}^{2} - 4x + {1}^{2} \\ \Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ {4x}^{2} - 4x + 1 }}}\end{gathered} }$

$\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$
