When the expression (2x^4+3x^3+x-14)(3x^{10}-9x^7+9x^4+30)-(x^2+5)^8 is expanded, what is the degree of the resulting polynomial?

Just look at the hoghest powers

 

2x^4 * 3x^10 = 6x^14

6x^14 ..... -   x^16 .....

Highest power of x will be 16     The leading term will be    -x^16

 

the degree is 16
