Answer:</h2><h2>Yes, the simplified form of 2 square root of 3 − 2 square root of 3 is rational.</h2>
Step-by-step explanation:
The given expression is 
After performing the subtraction operation, the result is 0 as the terms are equal and opposite in sign, they cancel each other.
Rational numbers are those which can be expressed in the form of fractions, decimals, e.t.c
Since 0 can be expressed as a fraction, it is a rational number.
For eg:
= 0,
Hence the result of the given expression is a rational number.
Subtract 8 from both sides
So you end up with x = -23
