What are the solutions?
x1= Round your answer to 3 significant figures.question.score feedback.none Expected answer:
x2= Round your answer to 3 significant figures.question.score feedback.none Expected answer:
The quadratic formula is
x=−b±√b2−4ac2a
So in this case this gives
x=−(31)±√(31)2−4×(5)×(34)2×(5)
Giving
x=−31±√28110
So
x=−31−√28110andx=−31+√28110
x1=−4.78andx1=−1.42
