Por favor me ajudem!!!

Answer 1

Olá Samira,

aplique a distributiva:

$(a^2-1)(2a^2-2a+1)~~~~.\\ a^2\cdot 2a^2+a^2\cdot(-2a)+a^2\cdot1-1\cdot2a^2-1\cdot(-2a)-1\cdot1\\ 2a^4-2a^3+a^2-2a^2+2a-1\\\\ Reduza~os~termos~semelhantes:\\\\ \Large\boxed{\boxed{\boxed{2a^4-2a^3-a^2+2a-1}}}.\\.$

Tenha ótimos estudos ;D
