Answer:
The original equation must have been:
Step-by-step explanation:
A quadratic equation is in the form of :
And it is solved in the form of :
and
Now the given equation is :
We can see that here;
a = 7
b = -5
c = -2
So, the original equation must have been:

Answer:
The theoretical probability is 1/18
Step-by-step explanation:
Firstly, we need to know the total number of possible results
By rolling two cubes, there are a total of 36 possible results
Now, the sum of 3 can be gotten by the addition of 1 to 2 or 2 to 1
If we have 1 on the first cube and 2 on the second, we have the correct sum
we can also have 2 on the first cube and 1 on the second
This gives a total of 2 possible ways of getting 3
The probability can be calculated by dividing the number of ways to get 3 by the total number of possible results
we have this simply as 2/36 = 1/18
