    Answer:

    Consider the polynomial:

    y=3×2−2x+4

    The coefficient of x is −2 .

    The coefficient of x2 is 3

    For a general function f(x) , we can expand in terms of the (an extension of the idea of a Taylor series to include negative power terms):

    f(x)=∑n=−∞+∞(anxn)

    The “coeffecient of xn ” is then trivially given by an

    For example, the expansion of the polynomial up there is simply given by:

    a0=4

    a1=−2

    a2=3

    an=0 n≠0,1,2

    And so we see that we recover the coefficient of x2 is 3, as we said above.

    The specific case you have given is:

    an=2(if n = -1)

    an=0(else)

    the co-efficient of x^2 and x in

    x²+x+1 are

    1, 1 .

    coefficient is a number multiplied with a variable.
