Question

the coefficient of x^3 in polynomial 2-x^3+x^3-x^7 will be​

Answer 1

Answer:

-7 is the answer

Step-by-step explanation:

Clearly −7 is the constant multiplied with x 3

Hence, coefficient of x 3

is −7.

Answer 2

Answer:0

Step-by-step explanation:

$2-x^3+x^3-x^7 = 2-x^7$

We can see that $+x^3-x^3$ are cancelled. So there is no coefficient of $x^3$ in the polynomial.
