Question

(x+3)(x−3)=

anybody know what this is equal to? all i've been seeing is 3x3x3x3x3

Answer 1

Explanation:

Expanding the expression (x+3)(x-3) using the FOIL method, we get:

(x+3)(x-3) = x(x) + x(-3) + 3(x) + 3(-3)

Simplifying the above expression, we get:

(x+3)(x-3) = x^2 - 9

Therefore, (x+3)(x-3) is equal to x^2 - 9, not 3x3x3x3x3.
