identify the parts of the following expression
5x^2+4x+15
what is the constant
what is the variable
what is the exponent
whaat is the coefficient of the second term
Constant: 15
Variable: x
Exponent: 2
Coefficient of the second term: 4
The given expression is 5x^2 + 4x + 15.
Parts of the expression:
- Constant: The constant is a term that does not have any variables. In this expression, the constant is 15.
- Variable: The variable is the symbol used to represent an unknown value. In this expression, the variable is "x".
- Exponent: The exponent is the power or index to which a variable is raised. In this expression, the exponent is 2.
- Coefficient: The coefficient is the numerical factor multiplied by a variable. It is the number in front of a variable. In this expression, the coefficient of the second term (4x) is 4.
To identify the different parts of the expression 5x^2+4x+15, let's break it down:
1. Constant: In this expression, the constant is the term without any variables attached to it. In this case, the constant is 15.
2. Variable: The variable is the letter or symbol used to represent an unknown value. In this expression, the variable is 'x'.
3. Exponent: The exponent refers to the power to which a variable is raised. In this expression, the variable 'x' is raised to the power of 2. Hence, the exponent is 2.
4. Coefficient of the second term: A coefficient is the numerical factor that multiplies the variable. In this expression, the second term is 4x. The coefficient of the second term is therefore 4.
So, to summarize:
- Constant: 15
- Variable: x
- Exponent: 2
- Coefficient of the second term: 4
