Best ResponseYou've already chosen the best response.2That'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.

Best ResponseYou've already chosen the best response.0Well the equation is set up as (a+1) (a7) thats what I got. but 17=6 so that doesnt work.

Best ResponseYou've already chosen the best response.2No problem. We've all had something obvious pass us by before :P

Best ResponseYou've already chosen the best response.0would the solution set be written as (a+7) (a1) or just {7,1}

Best ResponseYou've already chosen the best response.0are you factorizing? normally it wuold be written as full.

Best ResponseYou've already chosen the best response.0you could always use the quadratic formula \[t=\frac{b\pm\sqrt{b^24ac}}{2a}\]

Best ResponseYou've already chosen the best response.0(a+7)(a1) that is.... you will need to use the full factors to use in equations.

Best ResponseYou've already chosen the best response.2The solution set would be {7,1}. Note that you have 7 and +1 because if \(a+7=0\), then \(a=7\). Similarly, \(a1=0\implies a=1\).

Best ResponseYou've already chosen the best response.0@Ben103 sorry the questions look like what I'm doing at school at the moment which is factorizing :( I could be wrong

Best ResponseYou've already chosen the best response.2As 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.
