Question

Simplify : - ( x + 4) ( x- 4)​

Answer 1

Answer:

x² - 16

Step-by-step explanation:

$\implies (x+4)(x-4) \\ x(x-4)+4(x-4)\\x^2-4x+4x-16\\x^2-16 \\\\ you \ can \ also \ solve \ by \ using \ identity, \\ (a+b)(a-b)=a^2-b^2 \\\\ =>(x+4)(x-4)\\=>x^2-4^2 \\ =>x^2-16$

Answer 2

Answer:

$(x + 4)(x - 4) = {x}^{2} - {4}^{2} = {x}^{2} - 16$
