Question

Pls help im a little bit sтuрid

Answer 1

Explanation:

a⁴+16a²b-2ab-a²+64b²-b²

we can also write them as,

a⁴+16a²b+64b²-a²-2ab-b²

Now, from -a²-2ab-b² if we take - as common term then we get,

a⁴+16a²b+64b²-(a²+2ab+b²)

Now, by using the concept of a²+2ab+b²=(a+b)²

(a²)²+2×a²×8b+(8b)²-{(a)²+2×a×b+(b)²}

(a²+8b)²-(a+b)²

I hope it helped U
