Question

(a^4 - a^2b^2 + b^2)(a^2 + b^2)

find the product​

Answer 1

Answer:

ANSWER

=(a+b)(a−2b)=a×a+b×(−2b)+b×a+a×(−2b)

=a

2

−2b

2

−ab

a=1,b=2

=1−2×2

2

−1×2

=−9

Answer 2

Answer:

a6−a2b4+a2b2+b4

Step-by-step explanation:

(a4−a2b2+b2)(a2+b2)

=(a4+−a2b2+b2)(a2+b2)

=(a4)(a2)+(a4)(b2)+(−a2b2)(a2)+(−a2b2)(b2)+(b2)(a2)+(b2)(b2)

=a6+a4b2−a4b2−a2b4+a2b2+b4

=a6−a2b4+a2b2+b4
