To "evaluate" an expression, you need to know the value for the variables.
If you mean: x2+12x+35 then it is a quadratic expression that can be factored as: (x+5)(x+7)
The expression x2 + 3x +8 is a quadratic trinomial.
"Evaluate" means to calculate - find out what value it has.
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
