8c + 5 = 4c - 11Subtract 4c from each side:4c + 5 = -11Subtract 5 from each side:4c = -16Divide each side by 4:c = -4
24c2 + 96c + 90 = 6*(4c2 + 16c + 15) = 6*(2c + 3)*(2c + 5)

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4 20c + 5 = 5c +65 20c - 5c= 65 - 5 15c = 60 15c/15 = 60/15 c = 4 (alternative method)
5.25, or 5 and 1 quarter (5 1/4)
8c2-26c+15 8c2-6c-20c+15 2c(4c-3)+5(-4c+3) (2c-5)(4c-3)
8c + 5 = 4c - 11Subtract 4c from each side:4c + 5 = -11Subtract 5 from each side:4c = -16Divide each side by 4:c = -4
2c + 4 - 3c = -9 + c + 5 -c + 4 = c - 4 -2c = -8 2c = 8 c = 4
20+40c is the answer.
24c2 + 96c + 90 = 6*(4c2 + 16c + 15) = 6*(2c + 3)*(2c + 5)
-((3c - 4)(3c + 4)(2c - 5)(2c + 5))
14c+33-10c=5 4c+33=5 4c=-28 c=-7

It depends on the value of c. If c = 0 then 0-0+5 = 5 If c = 1 then 1-2+5 = 4 If c = 2 then 4-4+5 = 5 and so on.
