As per the given expression, the numerator is (2x² + x - 3).
What is a numerator?
In a fraction, the number is over the line, is called the numerator.
The given expression:
[( x + 2 ) / 3] - [( x + 1) / 2x]
= [2x(x + 2) - 3( x + 1)] / 6x
= (2x² + 4x - 3x - 3) / 6x
= (2x² + 4x - 3x - 3) / 6x
= (2x² + x - 3) / 6x
Here, least common denominator is 6x.
Therefore, numerator is (2x² + x - 3 ).
