Пошаговое объяснение:
1) [tex]a^{2}[/tex] - [tex]b^{2}[/tex] = (a-b)(a+b)
2)[tex]a^{2}[/tex] -4= [tex]a^{2}[/tex] -[tex]2^{2}[/tex]= (a-2)(a+2)
3) 9-[tex]x^{2}[/tex] = [tex]3^{2}[/tex] -[tex]x^{2}[/tex] = (3-x)(3+x)
4) [tex]m^{2}[/tex] -[tex]n^{2}[/tex] = (m-n)(m+n)
5) 25-[tex]m^{2}[/tex] = [tex]5^{2}[/tex] - [tex]m^{2}[/tex]= (5-m)(5+m)
