A:
Answer:5+√97/4 Also 5-√97/4Step-by-step explanation:The Quadratic formula is x=-b+-√b^2-4ac/2aThis means that we should plug the values for A B AND C into the formulaWe can work out that A = 2B=-5C=-9Once we have put these into the formula we get 5+√97/4 (all over 4) aka 3.71Also 5-√97/4 (all over 4) aka -1.21
