Question

write the coefficient of X^3cube for the following polynomials
a)1+x^2+x^4-x-x^3
b)2x^3-7x+x^2+3x^4
c)x/2-x^2/3+x^3/4
d)4x+x^3+x^6-7x^2
e)5x^3+2x-x^2-x^5​

Answer 1

Answer:

Step-by-step explanation:

for (a) -1  is the coefficient since there is no other constant before x^3                                    

     (b) 2 is the coefficient since it is before x^3

     (c) 0 since there is no x^3 in the question.

     (d) 1 since no other constant is present in front of x^3

     (e) 5 is the coefficient as it is the only constant present in front of x^3

hope it helped :)
