(4x+3)²

Answer 1

$\large\bm{\left(4x + 3\right)^{2} } \\\\ \large\bm{\left(4x\right)^{2} + 2 \times 4x \times 3 + {3}^{2} } \\ \large\bm{16 {x}^{2} + 2 \times 4x \times 3 + {3}^{2} } \\ \large\bm{ {16x}^{2} + 24x + {3}^{2} } \\ \bm{\large\boxed{\boxed{  { \large \bm{ {16x}^{2} + 24x + 9 }}}}}$

${\large\boxed{\boxed{  { \large \bm{ Bons~Estudos} }}}}$
