2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----

plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).
Positive (Plus) times Negative (Minus) always equals a negative (minus).

Yes it does. A minus is the opposite of something, so the minus of a minus is a plus.
