what is the excluded values for the fraction a
---
3-2a
To find the excluded values for the fraction, we need to determine the values of "a" that make the denominator equal to zero.
In this case, the denominator is 3 - 2a. To find the excluded values, we set the denominator equal to zero and solve for "a".
3 - 2a = 0
To isolate "a", we can subtract 3 from both sides of the equation:
-2a = -3
Next, we divide both sides of the equation by -2 to solve for "a":
a = -3 / -2
Simplifying further gives us:
a = 3/2
Therefore, the excluded value for the fraction is a = 3/2.
To summarize, the fraction is undefined when "a" is equal to 3/2, or in other words, 3/2 is the excluded value for this fraction.
