Question

Simplify: 2x^2 - 6x^2

Answer 1

`2x^2-6x^2=-4x^2`

Step-by-step explanation

Given:

`2x^2-6x^2`

To simplify the expression, we can find a common factor between the terms given, which, in this case, is x²:

`=x^2((2x^2)/(x^2)-(6x^2)/(x^2))`
`=x^2(2-6)`

Then, we can add two to –6, obtaining -4:

`=x^2(-4)`

Multiplying both factors we get:

`=-4x^2`
