Inequality
Simplify !
you have to deduce the variable and evaluate the expression.
You evaluate it.
you have to use "order of operations"
You evaluate the expression !! :)
Inequality
Evaluate.
You cannot find the answer to an expression!!! An expression needs to be EQUATED' to a value, for another value to be found. 2x^(2) + 5x + 12 is an EXPRESSION. Impossible to find an value for 'x'. However, 2x^(2) + 5x + 12 = 0 is an EQUATION and a result can be calculated.
