Answer:
Steps-by-step explanation:
So first you have to set the equation = 0
5c^2 - 26c - 24 = 0
Now you need to fact the equation.
You should get.
(5c + 4)(c - 6) = 0
After this you solve both equations:
5c + 4 = 0
5c = -4
c = -4/5
Then the next one.
c - 6 = 0
c = 6
And there is your answer
c = -4/5 and c= 6
