Answer:
[tex] \boxed{ \bold{ { \boxed{ \sf{(11y + m)(11y - m)}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{121 {y}^{2} - {m}^{2} }[/tex]
[tex] \longrightarrow{ \sf{ {(11y)}^{2} - {(m)}^{2} }}[/tex]
Use the formula of a² - b² = ( a + b ) ( a - b )
[tex] \longrightarrow{ \sf{(11y + m)(11y - m)}}[/tex]
Hope I helped!
Best regards
