Answer:
The missing term is 2x^2.
Step-by-step explanation:
The given expression is (10x - 4x^2) - (7x +___) = 3x - 6x^2
Let's take the missing term "a"
10x - 4x^2 - 7x - a = 3x - 6x^2
Simplify the like terms
3x - 4x^2 - a = 3x - 6x^2
3x -3x - 4x^2 +6x^2 = a
0 + 2x^2 = a
a = 2x^2
Therefore, the missing term is 2x^2.
Thank you.
