Common denominator is 15 so we have : (3 (x + 2) + 5 (x - 1))/15
ie (3x + 6 + 5x - 5)/15
ie (8x + 1)/15
Is there an equality missing somewhere?
You have to put your heart into it!
you use the quadratic formula: x= -b plus/minus the square root of b^2 - 4ac all over 2a. use this site to help you out: wolframalpha.com
if the question u are asking is something like this 1/2 - ( - 1/2 ) then the answer is simple all you have to do is solve the equation like this 1/2 - ( - 1/2 ) = 1/2 + 1/2 = 2/2 = 1 its the - (-1/2) that is important remember the rule minus and minus equal plus plus and plus equal plus minus and plus equal minus remember and i hope it helps :)
negative b plus or minus the square root of b squared minus 4AC all over 2 A
It is impossible to solve for n if there's nothing to equate it with. No could be any number each except for -4. All we know is n = n

In such cases, there is usually a discontinuity when the denominator is zero. In other words, solve for:x + 2 = 0
negative b plus or minus the square root of b minus 4 times ac all over 2 a
negative b plus or minus the square root of b squared minus 4AC all over 2 A
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
first of all, what is a plu? but the answer is (-8)+f+1/x sqared by the way, what grade are you in?
The least common denominator is 24x. If all of that equals zero, x = 3/20
All should be around 125 psi plus or minus 25%All should be around 125 psi plus or minus 25%

What happens is when a goal is scored, all the players on the scoring team get plus one on their plus-minus rating, and all the players on the scored on team gets minus one on their rating. signed Hockey Man
