Oh, dude, we're diving into some math here! So, when you have -2x minus -2, you can simplify it by adding the opposite of that second negative, which is like adding a positive. So, it becomes -2x + 2. Math can be a trip, man!

Oh, what a happy little question we have here! When we have -2x minus -2, we can simplify it by adding 2 to the negative 2, which gives us -2x + 2. Remember, in the world of math, there are no mistakes, just happy little accidents!
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
(2x - 7)(x + 1)
I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
x - 2 = 0 if x = 2 So put x = 2 into 3x3 - 2x + 2 ie 24 - 4 + 2 = 22
x(3x - 2)
