I couldn't find the sets of factors that add up to -13 in this problem. Plz help, anything is greatly appreciated!
Thx for helping ppl!
you could use the quad. eqn which is -b plus or munus sq root of b squared minus 4 ac all over 2 a
That is a good idea but I need to solve it by factoring, which uses a different method of solving it. Thx for helping out though, rach!
