Simplify (x+2)(x-2)
Problem
Solution
Identify the expression as a product of two binomials in the form
(a+b)*(a−b) Apply the formula for the difference of squares, which states
(a+b)*(a−b)=a^2−b^2 Substitute
a=x andb=2 into the formula.Calculate the squares to get
x^2−2^2 Simplify the constant term to reach the final expression.
