Answer:

[a4–6a2b2+b4 +(–2a4+5a2b2+3b4)] - (–a4–a2b2–4b4)

= (-3a4-a2b2+4b4) - (-a4-a2b2-4b4)

= -3a4+a4-a2b2+a2b2+4b4+4b4

= -2a4 + 8b4.

INDIAN WEAVERS Weavers, weaving at break of day, Why do you weave a garment so gay? Blue as the wing of a bluebird wild, We weave the robes of a new-born child.

Weavers, weaving solemn and still, What do you weave in the moonlight chill?
