The solutions to the equation are 
.
You can find the answer to any quadratic by using the quadratic formula. The formula is below.
Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.
A half life means that half the sample decays.
If the sample size is 1 , then after one half life there would be x * 1/2 = 1/2 of the sample left.
For the 2nd half life, multiply 1/2 by 1/2 to get 1/4.
So after 2 half lives, there is 1/4 of the sample left, which means 3/4 of the sample decayed.
The answer is 3/4
Yes because 484 + 484 equals 964
And equation you should always do the opposite of the sign you get to find your answer so he got minus he should use Addition
