Option (3) is correct.

The factored form of given equation is

Step-by-step explanation:

Given : equation

We have to factorize the given equation completely.

Consider the given equation

Using algebraic identity

We have ,

can be written as

Applying above idenity, we have,

Thus, the factored form of given equation is

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
