Which equation is represented by the model? 3x2 – 4x – 1 = (3x + 1)(x – 1) 3x2 – 2x – 1 = (3x – 1)(x + 1) 3x2 – 4x + 1 = (3x – 1)(x – 1) 3x2 – 2x + 1 = (3x – 1)(x – 1)

The correct option is 3.

Step-by-step explanation:

In option 1,

The given equation is

Simplify the right sides.

Since left hand side is not equal to right hand side, therefore option 1 is incorrect.

In option 2,

The given equation is

Simplify the right sides.

Since left hand side is not equal to right hand side, therefore option 2 is incorrect.

In option 3,

The given equation is

Simplify the right sides.

Since left hand side is equal to right hand side, therefore option 3 is correct.

In option 4,

The given equation is

Simplify the right sides.

Since left hand side it not equal to right hand side, therefore option 4 is incorrect.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
