Answer:
[tex]3(5n - 2) \times (2n - 5)[/tex]
Step-by-step explanation:
[tex]30 {n}^{2} - 87n + 30[/tex]
[tex]3(10 {n}^{2} - 29n + 10)[/tex]
[tex]3(10 {n}^{2} - 4n - 25n + 10)[/tex]
[tex]3(10 {n}^{2} \times (5n - 2) - 25n + 10)[/tex]
[tex]3(2n \times (5n - 2) - 5(5n - 2))[/tex]
[tex] = 3(5n - 2) \times (2n - 5)[/tex]
