Question

What is the missing term? (10x-4x^2)-(7x+?)=3x-6x^2

Answer 1

                                                         

The given problem is =

$( 10x-4x^{2} )-(7x+?)=3x-6x^{2}$

Lets suppose the missing term to be T

So equation becomes:

$10x-4x^{2} -7x-T=3x-6x^{2}$

$T=10x-4x^{2} -7x-3x+6x^{2}$

$T=2x^{2}$

Hence, the missing term is $2x^{2}$

Answer 2

The answer is 2x^2
Because everything on the right of the minus sign will turn negative
