Answer:

The sum of coefficients = 9

Step-by-step explanation:

The given expression is,

3x⁴ + 5x² + x

There are three terms in the given expression. All the terms contains variable x.

To find the coefficients of each terms

term        coefficients

3x⁴            3

5x²            5

x               1

To find the sum of coefficients

sum = 3 + 5 + 1 = 9

Therefore the sum of coefficients = 9

Hello!

The answer is: 9

Why?

To find the sum of the coefficients of the polynomial we have, we need to evaluate [tex]x=1[/tex]

So,

[tex]3(1)^4+5(1)^2+1=9[/tex]

The sum of the coefficientes of the expression is 9

Have a nice day!
