Select the term that describes the linear portion in this quadratic equation 7x² - 12x + 16 = 0
-12x, 7x², 16, None of the above

Solution:

Given: Equation is 7x² - 12x + 16 = 0

A linear term is a term with a degree of 1, or simply x.

Here, in the given equation 7x² is a quadratic term because the x has a degree of 2,

and the 16 is just a constant.

-12x is the linear term because its degree is 1 (x¹ or simply x).

Hence, the term -12x describes the linear portion in this quadratic equation 7x² - 12x + 16 = 0

Select the term that describes the linear portion in this quadratic equation 7x² - 12x + 16 = 0

Summary:

The term -12x describes the linear portion in this quadratic equation 7x² - 12x + 16 = 0.
