That's just you :) There are indeed two numbers that multiply to be -7, and add to be 6. Think about it a bit and I'm sure you'll get it.

Well the equation is set up as (a+1) (a-7) thats what I got. but 1-7=-6 so that doesnt work.

remember that - and + in front of the numbers

Thanks lol I cant believe i cudnt figure tthat out

No problem. We've all had something obvious pass us by before :P

would the solution set be written as (a+7) (a-1) or just {7,-1}
anonymous
  • anonymous
are you factorizing? normally it wuold be written as full.

you could always use the quadratic formula \[t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

(a+7)(a-1) that is.... you will need to use the full factors to use in equations.

The solution set would be {-7,1}. Note that you have -7 and +1 because if \(a+7=0\), then \(a=-7\). Similarly, \(a-1=0\implies a=1\).

@Ben103 sorry the questions look like what I'm doing at school at the moment which is factorizing :( I could be wrong

@KingGeorge knows more than me i'm sure! lol I'm only doing high school maths

As another tip, if you're asked for a solution SET, your final answer should look like {_,_,_,...,_}. I.e., you have a list of things in the curly brackets.
