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

Step-by-step 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
