im \: guessing \: its \: 4x {}^{2}  - 3x + 1 \\ (correct \: me \: if \: im \: wrong)

(a - b) {}^{2}  = a {}^{2}   - 2ab +  {b}^{2}

4x {}^{2}  = a {}^{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: b {}^{2}  = 1 \\ a = 2x \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \: b = 1

(2x - 1) {}^{2}  = 4x {}^{2}   -4x + 1

we \: need \: to \: add \: a \: - x \\ \: to \: the \: original \: equation

<h2>Note that this problem can be approached in many ways. For instance, we can add to the b² term instead of changing the middle term...</h2>
