The subtraction of the given expression will be (x²-9x +1).
<h3>What is subtraction?</h3>
The method of removing or deleting anything from the given set will be defined as subtraction. It is represented by the negative sign '-'.
The subtraction will be calculated as:-
E = (–3x² + 7 – 2x) – (6 + 7x – 4x²)
Arrange the terms in the above expression.
E = ( -3x²+4x²-2x-7x-6+7)
E = ( x² - 9x + 1 )
Therefore the subtraction of the given expression will be (x²-9x +1).
