Simplify the expression state any excluded values
2a^2-4a+2

3a^2-3

The simplified form is .

is the excluded value for the given expression.

Step-by-step explanation:

Given:

The expression given is:

Let us simplify the numerator and denominator separately.

The numerator is given as

2 is a common factor in all the three terms. So, we factor it out. This gives,

Now,

Therefore, the numerator becomes

The denominator is given as:

Factoring out 3, we get

Now, is of the form

So,

Therefore, the denominator becomes

Now, the given expression is simplified to:

There is in the numerator and denominator. We can cancel them only if as for , the given expression is undefined.

Now, cancelling the like terms considering , we get:

Therefore, the simplified form is

The simplification is true only if  . So, is the excluded value for the given expression.
