this problem is asking for the solution so you question is given in standard form you might be asking yourself which method do I use you cannot fact is he question because when B&C are the same they cannot be factored you can try to complete the square but when B is odd you are a given a fraction and this your problem more difficult to complete if he is a quadratic formula you can solve through the entire problem the quadratic turn that is written in Orange all you need to do is plug in the a b and C's and solve all the way through from this we are left with -3 plus or minus the square root of 9 - 24 all / 4 produces itself to -3 plus or minus the square root of -15 all over 4 square root of -15 can be broken down into two smaller factors  these factors include the square root of -1 and the square root of 15 the square root of -1 is I but the square root of 15 cannot be reduced and further  so we are left with -3 + minus the square root of 15  all over for  because of the puss in mine we must separate this into two separate Solutions first Solutions beat being -3 plus I the square root of 15 all over 4  + -3 -  I in the square root of 15 all over for
