Question

Joanna and linne were trying to describe parts of the expression 3x2+x+5

Answer 1

The expression 3x^2 + x + 5 consists of three terms: 3x^2, x, and 5. Each term represents a different part of the expression: quadratic, linear, and constant.

Step-by-step explanation:

The expression 3x2 + x + 5 consists of three terms: 3x2, x, and 5. Each term represents a different part of the expression. Let's break them down:

1. 3x2: This term is a quadratic term because it contains the variable x raised to the power of 2. It represents the square of a number multiplied by a variable. For example, if x = 2, then 3x2 = 3(2)2 = 3(4) = 12.
2. x: This term is a linear term because it contains the variable x raised to the power of 1. It represents the product of a number and a variable. For example, if x = 2, then x = 2.
3. 5: This term is a constant term because it doesn't contain any variables. It represents a fixed value. In this case, the value is 5.
