What is subtraction?

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).
