Question

multiply ax+3 and ax-3 by using formula

Answer 1

(ax + 3)(ax - 3)

Keeping (ax - 3) common

= ax (ax - 3) + 3 (ax - 3)

= a²x² - 3ax + 3ax - 9

Cancelling - 3x and + 3x

= a²x² - 9

Answer 2

Answer:

ax²- 9

Step-by-step explanation:

(ax+3)(ax-3)

By using (x+y)(x-y)= x²- y²

where x=ax and y=3

Therefore by substituting the values we get,

(ax+3)(ax-3)= ax²- 3²

                  = ax²- 9
