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

Solution:

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

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 -2x² = -2 × x²

Therefore, the coefficient of x² is -2.
