20c^2 - 39c + 18 = 0. The solution(s) is/are c = ??? Simplify your answer.
Added by Brianna R.
Step 1
We can do this by finding two numbers that multiply to 20*18=360 and add up to -39. These numbers are -15 and -24. So, we can rewrite the equation as: (20c - 15)(c - 3) = 0 Now, we can solve for c by setting each factor equal to zero: 20c - 15 = 0 or c - 3 = Show more…
