Why are negative numbers in brackets positive but positive numbers in brackets are not negative?
'cuz
What is the difference if the negative sign is inside or outside of the brackets in algebra?
If the negative sign is inside the brackets, for example: [-2(9)] it is a negative two and you times that by positive nine. But if it were -[2(9)] than you times two by nine and get eighteen, THEN the eighteen takes on the negative. So basically, if the negative sign is inside the bracket, then it will only affect the number it is closest to, but if it is outside the brackets, it affects all over the numbers inside of it.
What is the difference in algebra if the negative sign is inside or outside the brackets?
If it's inside the brackets it means that it belongs to that specific term, but if it was outside the brackets, it means that every term inside the brackets goes out with opossite sign. For example: [ -5x + 6y ] = -5x + 6y , the negative is only for 5x, but if you had - [ -5x + 6y] = 5x - 6y , every term inside the bracket goes out with opossite sign.
You are about 2 factor a quadratic equation involving some xs and a plan number you see that the sign in front of the xs is negative and the sign in front of the plan number is positive this tells you?
That means that both of your brackets will have minus signs.
What is a negative number divided by a negative number?
A negative number divided by a negative number is a positive number.
