Simplify:
2xsquared minus 4xsquared
-12x
2x^2 - 4x^2 = -2x^2.
Henry is right.
To simplify the expression 2x^2 - 4x^2, we can combine like terms by subtracting the coefficients of x^2.
First, let's rewrite the expression:
2x^2 - 4x^2
Now, we can combine the x^2 terms:
2x^2 - 4x^2 = (2 - 4)x^2
Simplifying further, we have:
2x^2 - 4x^2 = -2x^2
So, the simplified expression is -2x^2.
