Plug in the 1/2 where the a’s are answer is -3
Sub values a=3 b=-6 c=8 in quadratic formula and solve for x
Answer:
23/16
Just set the missing fraction has X, and multiply the numerator and denominator of 3/2 by 8 so that it equals 24/16. This way you can isolate X and get x=23/16. It can't be simplified further, so that should be your final answer.
