$\textit{(m−4)(m+6)}$

$\textit{=(m+ −4)(m+6)}$

$\textit{=(m)(m)+(m)(6)+(−4)(m)+(−4)(6)}$

$\textit{=m^2+6m−4m−24}$

$\textit{=m^2+2m−24}$

$\textit{(13+x)(13−x)}$

$\textit{=(13+x)(13+ −x)}$

$\textit{=(13)(13)+(13)(−x)+(x)(13)+(x)(−x)}$

$\textit{=169−13x+13x−x^2}$

$\textit{=−x^2+169}$

$\textit{Hope this helps you}$
