Write the coefficient of x² of the following : 3x - 5

Solution:

Given, the polynomial is 3x - 5

We have to find the coefficient of x²

3x - 5 is a linear polynomial with the highest degree of exponent as one.

So, x² term is not possible.

Therefore, the coefficient of x² is zero.

✦ Try This: Write the coefficient of x² of the following : 4x² - 5x

Given, the polynomial is 4x² - 5x

We have to find the coefficient of x²

4x² - 5x is a quadratic polynomial with the highest degree of exponent as two

Therefore, the coefficient of x² is 4.
