What is the exponent: 2
What is the coefficient of the second term: 4
To identify the parts of the expression 5x^2 + 4x + 15:
- The constant is the term that does not contain a variable. In this expression, the constant is 15.
- The variable is represented by the letter 'x'.
- The exponent is the number that appears above the variable. In this expression, the exponent of 'x' is 2.
- The coefficient is the numerical value that multiplies the variable. The second term is 4x, and the coefficient of this term is 4.
To identify the parts of the expression 5x^2 + 4x + 15, we need to understand the different elements involved in the expression.
1. Constant: A constant value is a number that does not change and has no variables attached to it. In this expression, the constant is 15 since it is a fixed value.
2. Variable: A variable is a letter or symbol that represents an unknown value or can take on different values. In this expression, the variable is 'x'.
3. Exponent: An exponent is a number that represents how many times a variable is multiplied by itself. In this expression, the exponent is 2, indicated by the '^2' after 'x'.
4. Coefficient: A coefficient is the numerical factor that is multiplied by a variable. In this expression, the coefficient of the second term (4x) is 4.
Therefore, for the expression 5x^2 + 4x + 15:
- Constant: 15
- Variable: x
- Exponent: 2
- Coefficient of the second term: 4
