Answer:
-0.56 or -10.67 (rounded to nearest hundredth)
Step-by-step explanation:
quadratic formula is (-b +/- √(b^2 - 4ac))/2a, so
[tex]\frac{-45 +/- \sqrt{45^{2} - 4(4)(24)}}{2(4)}[/tex]
which equals
[tex]\frac{-45 +/- 40.51 (rounded)}{8}[/tex]
when you simplify this, you should get
-0.56 or -10.67
