Question

Simplify using the identity a2-b2=(a+b)(a-b) for (3x+4)(3x-4)​

Answer 1

Answer:

(3x + 4) (3x - 4) = ( 3x^2 - 4^2)

Step-by-step explanation:

by using (a+b)(a-b) property

as we multiply a from a we get a^2 and same goes for b

Answer 2

As we already know,

a²-b² = (a+b)(a-b)

Therefore,

(3x+4)(3x-4)

=3x²-4²

=3x²-(4×4)

=3x²-16
