4x2-6.5 = 2.5
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
You replace each variable by its value. Then you do the indicated calculations.
To evaluate an expression is nothing but to operate the given expression according to the operators given in the expression if it is evaluable i.e, it could be convertable.
An exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. In the expression 4x^2 (four x squared) the four is the coefficient and the 2 is the exponent.
Substitute the given value for the argument of the function.

-7
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
It is a combination of numbers and variables, linked together by mathematical functions. For example sqrt(2y/3*7.34*pi) where y is some variable. Given the value(s) of the variable(s) it is possible to evaluate (find the value of) the expression.
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
replace the variables with the given values and simplify using the order of operations.
