2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.

Answer:

The missing term is -2x²

Step-by-step explanation:

It is given that,

(10x - 4x² ) - (7x + ?) = 3x - 6x²

To find the missing term

Let 'M' be the missing term we can write the above equation,

(10x - 4x² ) - (7x + M) = 3x - 6x²

⇒ 10x - 4x² - 7x + M = 3x - 6x²

⇒ 10x - 7x - 4x² + M = 3x - 6x²

⇒ 3x - 4x² + M = 3x - 6x²

M = -6x² + 4x²

M = -2x²
