Answer:
[tex] \boxed{ \bold{ { \boxed{ \sf{2 {c}^{4} + 3 {c}^{3} - {13c}^{2} - 18c + 6}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{( {c}^{2} - 6)(2 {c}^{2} + 3c - 1)}[/tex]
Use distributive property
[tex]{ \sf{ {c}^{2} (2 {c}^{2} + 3c - 1) - 6(2 {c}^{2} + 3c - 1)}}[/tex]
[tex] \sf{2 {c}^{4} + 3 {c}^{3} - {c}^{2} - 12 {c}^{2} - 18c + 6}[/tex]
Collect like terms
[tex] \sf{2 {c}^{4} + 3 {c}^{3} - 13 {c}^{2} - 18c + 6} [/tex]
Hope I helped!
Best regards! :D
