Detailed Solution

Concept: Initially, set (x-8) to be t. As a result, the formula changes to t(x-2) , which can then be simplified by taking advantage of the distributive property of multiplication to get xt-2t. Put the value of t in the equation now, simplify it again by utilizing the distributive property of multiplication, and then go through the resulting expression to find the solution.
Let's begin by setting (x-8) to be t in order to solve the preceding problem. Therefore, we can state:
Question ImageSuppose we now insert the equation (x 8) (x 2) from the question. As a result, we obtain
Question ImageBy distributive rule of multiplication
The result of using this in our equation is xt-2t.
We will now replace the value of t in equation (1) . As a result, we have x(x-8) -2(x-8) .
Question ImageHence, the correct answer is option 1.
