Answer:
<h3>
Evaluating an expression</h3>
Unlike an equation, expression does not have an equal sign.
Example
(x² - 4²) / (x + 2)
So, by evaluating an expression it means to simplify the expression. Let's take a look at the example again
(x² - 4²)
= (x + 2)(x - 2) / (x + 2)
= (x - 2)
<h3>Solving an equation</h3>
Solving an equation involves finding an unknown value given in the equation. It contains an equal to sign (=) so, it result in a solution.
Example
(x² - 4²) / (x + 2) = 0
(x + 2)(x - 2) / (x + 2) = 0
(x - 2) = 0
x = 2
