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
Answer:
The sum of the coefficients of expression 3x⁴+5x²+x = 9 .
Step-by-step 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 .
