<h3>What is simplification of an expression?</h3>
Usually, simplification involves proceeding with the pending operations in the expression.
Simplification usually involves making the expression simple and easy to use later.
Both (x−3)(x+3) and (3−x)(3+x) contain a sum and a difference and have only 3 and x in each factor.
Let see the equation formed by the factor;
(x−3)(x+3)
= x^2 + 3x - 3x - 9
= x^2 - 9
(3−x)(3+x)
= 9 + 3x - 3x - x^2
= 9 - x^2
