What is the missing term? (10x - 4x²) - (7x + ?) = 3x - 6x²

Solution:

Given, (10x - 4x²) - (7x + ?) = 3x - 6x²

We have to find the missing term.

Let the missing term be a.

So,  (10x - 4x²) - (7x + a) = 3x - 6x²

10x - 4x² - 7x - a = 3x - 6x²

Grouping of common terms,

10x - 7x - 3x - a = -6x² + 4x²

10x - 10x - a = -2x²

- a = -2x²

a = 2x²

Therefore, the missing term is 2x².

What is the missing term? (10x - 4x²) - (7x + ? ) = 3x - 6x²

Summary:

The missing term of the equation (10x - 4x²) - (7x + ?) = 3x - 6x² is 2x².
