Question

use the identies and simplify. (x+3)(x-3)​

Answer 1

Answer:

HOW TO SOLVE

(x+3)(x-3)

This is in the form

(a+b)(a-b)

Now according to identities=

(a+b)(a-b)= $a^{2} -b^{2}$

= $x^{2} -3^{2}$

=$x^{2} -9$

CONFIRMATION

(x+3)(x-3)

= $x^{2} -3x+3x -9$

-3x and +3x get cancelled with each other

So what remains is $x^{2} -9$

Hope this helps u :)
