Question

What is the constant term in the algebraic expression $3x^2+5x+6?$

• A. $3x^2$
• B. $5x$
• C. $6$
• D. $5x+6$

Answer 1

The correct option is C $6$

$\underset{–}{\text{Constant:}}$
A constant in an algebraic expression involves only numbers. We call it constant because the respective term has always the same value across the expression.

In the expression $3x^2+5x+6,$

• The third term $6$ is a constant.
• $3x^2$ and $5x$ cannot be constants because for different values of the variable $x,$ we get different numerical values of $3x^2$ and $5x.$

Therefore, option (c) is the correct option.
