Answer:
1. [tex]44(a-1)(a+1)[/tex]
2. xyz ( x + y + z )
Step-by-step explanation:
1. [tex]44a^{2} -44[/tex]
[tex]44(a^{2} -1)[/tex]
[tex]44(a^{2} +a-a-1)[/tex]
[tex]44(a(a+1)-1(a+1))[/tex]
[tex]44(a-1)(a+1)[/tex]
2. [tex]x^{2} yz=[/tex] x × x × y × z = [tex](xyz)[x][/tex]
[tex]xy^{2} z=[/tex] x × x × y × z = [tex](xyz)[x][/tex]
[tex]xyz^{2} =[/tex] x × x × y × z = [tex](xyz)[x]\\[/tex]
[tex]x^{2} yz+xy^{2} z+xyz^{2} =(xyz) [ x + y + z ][/tex]
[tex]xyz ( x + y + z )[/tex]
