Question

p(x)81+27√2x^7-45 x^3-x^3+2x^2+5x-6+8÷3 find A. qn^-1 ,Qn^-3,Qn^-4 ,Qn^-4, Q0 ,B. Head of Coefficient C. degree of p(x) D. Coefficient of X^5 pls answer briefly

Answer 1

The given polynomial can be rewritten as

`p(x)=27\sqrt[]{2}x^7-46x^3+3x^2+(5x)/(3)+87`

From this form, we can see that

b) The leading coefficient is

`27\sqrt[]{2}`

c) the degree of p(x) is 7

d) the coefficient of x^5 is zero because there are not such term in the polynomial
