y^8 - 16y^5
Factor out common terms.
y%5E8y+-+16y%5E5=y%5E9-16y%5E5
y%5E8y+-+16y%5E5=y%5E5%28y%5E4-16%29
The term in parenthese is the difference of two squares,
y%5E8y+-+16y%5E5=y%5E5%28y%5E2%2B4%29%28y%5E2-2%29
The final term is also a difference of two squares,
y%5E8y+-+16y%5E5=y%5E5%28y%5E2%2B4%29%28y-sqrt%282%29%29%28y%2Bsqrt%282%29%29
