Question

What is the sum of coefficients of an algebraic expression $4x^3-3x+1?$

Answer 1

$\underset{–}{\text{Coefficient:}}$
A coefficient is the numerical factor of a term containing constant and variables. For example, in the term $2x,$ $2$ is the coefficient, depicted in the picture below.


In the given expression $4x^3-3x+1,$
Coefficient of $x^3=4$
Coefficient of $x=-3$,

Therefore, sum of all the coefficients $=4+(-3)=4-3=1$

Hence, the sum of all the coefficients is $1.$
