Question

Find the difference.
(2x2-x) - (x2 + 4x - 6)

Answer 1

Explanation:

I'm not sure if I'm reading this right, but let's see if this helps:

First we want to distribute the subtraction indicator, this will help with the rest:

2x^2 - x - x^2 - 4x + 6

The reason why there's a +6 is because subtracting a negative makes the number positive. Now we use arithmetic:

x^2 - 5x + 6

This is our new expression. Hope this helps!
