Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{25 {x}^{4} - 4}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{(5 {x}^{2} - 2)(5 {x}^{2} + 2)}[/tex]
Use the distributive property to multiply each term of the first binomial by each term of the second binomial.
[tex] \dashrightarrow{ \sf{5 {x}^{2} (5 {x}^{2} + 2) - 2(5 {x}^{2} + 2)}}[/tex]
[tex] \dashrightarrow{ \sf{25 {x}^{4} + 10 {x}^{2} - 10 {x}^{2} - 4}}[/tex]
Since two opposites add up to zero , remove them from the expression
[tex] \dashrightarrow{ \sf{25 {x}^{4} - 4}}[/tex]
Hope I helped!
Best regards! :D
