<u>Given</u>:
The quadratic equation is 
We need to determine the solutions of the quadratic equation.
<u>Solution</u>:
Let us solve the equation to determine the value of x.
Adding both sides of the equation by 5x and 3, we get;

The solution of the equation can be determined using quadratic formula.
Thus, we get;



Thus, the two roots of the equation are
and 
Hence, the solutions of the equation are
and 
Answer:
1020 raisins
Step-by-step explanation:
The problem tells you the number of raisins is proportional to the number of bags, so there will be "r" raisins in 12 bags:
r/12 = 680/8 = raisins/bag
r = (12/8)(680) = 1020
There will be 1020 raisins in 12 bags.
The answer is 300 divided by 20 which you would get 15.
