Pick an "x" value and then just do the math...

Explanation:

"Evaluate" needs to have some objective or criterion. Either the whole expression is equivalent to some other value or expression, or it simply needs numbers to put into the place of the variable.

Selecting #x = 2# for example, it would "evaluate" to:

#2(2−3)(2+3)+4 = 2(-1)(5) + 4 = -10 + 4 = -6#
