Question

Use the distributive property to multiply the expression. (x-3)(x+3)

Answer 1

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (x + 3)(x - 3)$

$= > \: \: x(x - 3) + 3(x - 3)$

$= > \: \: \: \: \: {x}^{2} \cancel{- 3x }+ \cancel{3x }- 9$

$= > \: \: \: \: \: \: \: \: \: \: \: \: {x}^{2} - 9$

Answer 2

Answer:

X^2-9

Step-by-step explanation:

(X-3)(X+3)

=X(X+3)-3(X+3)

=X^2+3X-3X-9

=X^2-9
