Answer:


\boxed{ \bold{ \huge{ \boxed{ \sf{25 {x}^(4) - 4}}}}}

Explanation:


\sf{(5 {x}^(2) - 2)(5 {x}^(2) + 2)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.


\dashrightarrow{ \sf{5 {x}^(2) (5 {x}^(2) + 2) - 2(5 {x}^(2) + 2)}}


\dashrightarrow{ \sf{25 {x}^(4) + 10 {x}^(2) - 10 {x}^(2) - 4}}

Since two opposites add up to zero , remove them from the expression


\dashrightarrow{ \sf{25 {x}^(4) - 4}}

Hope I helped!

Best regards! :D
