<span>Difference of squares method is a method that is used to evaluate the difference between two perfect squares.
For example, given an algebraic expression in the form:
can be factored as follows:

From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e.

which can be factored as follows:

The answer is 2.5 because the point is at the middle. Hope this’ll help
First add like terms in this case 1+7=8. Then then divide. 2x/8= 4. X=4
