Question

What is the sum of the coefficients of the expression 3x^4+5x^2+x?

Answer 1

The sum of the coefficients of expression 3x⁴+5x²+x = 9 .

Explanation:

We have given the expression:

3x⁴+5x²+x

We have to find the sum of coefficients of the expression.

There are three terms in this expression and all have variable x.

To find the coefficient of each term:

3x⁴ has coefficient 3, 5x² has coefficient 5 , x has coefficient 1 .

so, sum of coefficients of expression 3x⁴+5x²+x = 3+5+1 = 9 .

sum of coefficients of expression 3x⁴+5x²+x = 9 .

Answer 2

The sum of coefficients = 9

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
