X1=14a^5-27a^4b+21a^2b^2-8ab^4-3a^2b^2
X2=7a^3-3a^2b-ab^2
X3=2a^2-3ab+2ab^2
X4=a^2-ab+3b^2
X5=a^5+2ab-2b^2
X6=2a^4-3a^2b+a^2b^2+7ab^2+3b^4
Hallar:
Y= - X6 + X1 X3 +((X4 X5 -2)-X^2)

Answer 1

$y= -x_{6}+ x_{1}* x_{3} +((x_{4}* x_{5}-2)- x^{2} )$
-2a^4+3a^2b-a^2b^2-7ab^2-3b^4+ (14a^5-27a^4b+21a^2b^2-8ab^4-3a^2b^2 * 2a^2-3ab+2ab^2) + ((( a^2-ab+3b^2* a^5+2ab-2b^2) -2) -x^2

-2a^4+3a^2b-a^2b^2-7ab^2-3b^4+((14a^5-27a^4b+21a^2b^2-8ab^4-3a^2b^2  ) (2a^2-3ab+2ab^2  )  )+((((a^2-ab+3b^2  )(a^5+2ab-2b^2  )  )-2  )-x^2  )=29a^7-97a^6b+28a^6b^2+84a^5b^2-54a^5b^3-2a^4+36a^4b^2-54a^3b^3+20a^3b^4+2a^3b+3a^2b-5a^2b^2+24a^2b^5-16a^2b^6-7ab^2+8ab^3-9b^4-x^2-2
