Factor the expression below.
4x^2 - 1
a) (x-1)(4x-1)
b) (x-1)(4x+1)
c) (2x-1)(2x+1)
d) (2x-1)(2x-1)

C) (2x-1)(2x+1)

Step-by-step explanation:

APX

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

is should be y = 5x
