First put it in decreasing power according to x.
x^4-5x+8+x^2
=x^4+x^2-5x+8
Now this question is asking what is the highest degree of x you see in this function.
4 of course.
Therefore the answer to his question is degree of 4.
Done!
-4(4)=-16
3(1/7)=3/7
I think that’s what you are asking...
This is more or less how you write the question.
To solve it invert the 1/2 and multiply.
Which gives you 14 /8 whis is 1 3/4 cups.
