Answer 1

Question:-

Find the product of :- using in Identitie-

(2x - 6) (2x + 4)

Solution:-

_______________

=(2x - 6) (2x + 4)

=2x(2x+4)-6(2x+4)

=4x^2+8x-12x-24

=4x^2-4x-24

______________________________

we can also use the identity:-

(x-a)(x-b) = (ax)^2-bx+(ab)

So, using identity,

= 4x^2-4x-24

____________

Hence, done
