Use the discriminant to determine how many solutions there are to the equation.
-0.2xsquared+12x+11=0 Show your work.
-----
b^2-4ac = 12^2-4*-0.2*11 = 152.8
Since the discriminant is > 0, the equation has two unequal
Real Number solutions:
-------------------------------
Find the solution(s) to the equation. Is your answer in (c) correct?
--
x = [-12 +-sqrt(152.8)]/(-0.4)
---
x = [-12 + 12.36]/(-0.4) or x = [-12 - 12.36]/(-0.4)
