Question

The coefficient of x2 in p(x) = (3x + 7)3 is​

Answer 1

Answer:

there is no x square the co efficient is 0

Answer 2

Answer:

The coefficient of x2 in p(x) = (3x + 7)3 is 189.

Step-by-step explanation:

(a+b) ^3 = a^3+b^3+3a^2b+3b^2a

(3x+7) ^3 = (3x)^3 + 7^3 +3(3x)^2*7 + 3*7^2(3x)

(3x+7) ^3 = 27x^3 + 343 +189x^2 + 361x

The coefficient of x2 in p(x) = (3x + 7)3 is 189.

Coefficient*:

It is an integer that is multiplied by the variable and written next to it. The coefficient of a variables without a number is 1 . Coefficients are multipliers, but constants are fixed values.

In the above expression,

27 is the coefficient of x^3.

189 is the coefficient of x^2.

361 is the coefficient of x.
