$\huge\boxed{\fcolorbox{red}{Yellow}{Answer}}$

$\: \blue\bigstar \displaystyle \bf{(5x + 3)(2x + 4).... given \: equation}$

$\: \: \implies \displaystyle \sf{(5x + 3)(2x + 4)}$

$\\ \implies \displaystyle \sf{(5x(2x + 4) + 3(2x + 4))}$

$\\ \implies \displaystyle \sf{( {10x}^{2} + 20x + 6x + 12)}$

$\\ \implies \displaystyle \sf{ {10x}^{2} + 26 + 12}$

$\: \: \clubsuit\underline{\boxed{ \bf \color{gray} \: the \: answer \: will \: be \: {10x}^{2} + 26x + 12}}$
