\sqrt{4 \times 3}  -  \sqrt{4 \times 4 \times 3}  =

\sqrt{ {2}^{2} \times 3 }  -  \sqrt{ {4}^{2} \times 3 }  =

2 \sqrt{3}  -  4\sqrt{3}  =

Consider the function f(x)= x² - 4
Arisa [49]

Answer:

(X+2) (X-2) . This is the final answer

Step-by-step explanation:

Solving f(x) = x^2 - 4

A^2 - B^2 is a special case where the original equation before it was foiled is

(A + B) (A - B) because the middle terms will cancel out when foiled.

This means that the equation can be written as

(X + 2)(X - 2) = 0

Each of these you will then set equal to 0 and then solve

X + 2 = 0, X - 2 = 0

X = -2, 2

I hope this helps you! let me now if its right ok <3 :)
