Question

(11a^2b^2/2c-17x^2y^2/2z) (11a^2b^2/2c+17x^2y^2/2z)

using special products

Answer 1

Isn't that already a special product?

Answer 2

Because it's of the form (s+t)(s-t) it is equal to s^2-t^2.
So (121a^4b^4)/4c^2 - (289x^4y^4)/4z^2

Answer 3

not yet

Answer 4

- so if do you like it in this way .... like - for example : (a/b) - (c/d) multiplied with
((x/y)-(t/k)) and if you have thought it that firstly you make the substraction in paranthes and after you make the multiplication - like in this case what will result to you ((ad-bc)/bd) multiplied with ((xk-yt)/yk)
-so you have thought it in this way ?
