Write the coefficient of x² in the following: 1 + 2x + 3x² + 4x³

Solution:

Given, the expression is 1 + 2x + 3x² + 4x³

We have to find the coefficient of x² in the given expression

Coefficient is the numerical factor in a term

Sometimes, any factor in a term is called the coefficient of the remaining part of the term

From the expression,

We can observe that 3x² = 3 × x²

Therefore, the coefficient of x² is 3.
