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
<u>To find the missing term</u>
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
