2 QUESTION To solve this equation, we must simplify the left, set it equal to 0, and
then solve for x. Is the work below simplified correctly?
x + x2 - 2x - 2x +4 = 100
2x2 - 4x +4 = 100
-100 -100
2x2 - 4x-96 = 0
O True
O False

The first answer is true.

The common factor is 2. How you can determine this is looking at x( the first x to the power of 2. Compared to the rest of the equation you can divide 2 and it’ll give you one which is in it’s simplest form. Tip: the common factor will always be the lowest number which can divide each number.
