Question

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

Answer 1

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

Answer 2

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)`
