Write an expression to represent the sum of three times the square of a number and -7.
In your expression, what is the value of the constant?
3x^2 + (-7)
The expression to represent the sum of three times the square of a number and -7 is:
3x^2 - 7
In this expression, the constant value is -7.
To represent the sum of three times the square of a number and -7, we first need to assign a variable to the number. Let's use the variable 'x'.
The square of a number can be represented as 'x^2'.
Three times the square of a number can be represented as '3 * x^2'.
To find the sum, we add the result of '3 * x^2' with -7.
So the expression can be written as '3 * x^2 + (-7)'.
In this expression, the constant value is -7.
