Probability is the ratio of the times an event is likely to occur divided by the total possible events. In the case of our die, there are six possible events, and there is one likely event for each number with each roll, or 1/6. Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
The product of 14x25x4 is 1400 but I don't understand why you put use subtraction.
Answer:
Step-by-step explanation:
1) GCF = Greatest common factor which would be 6x so lets get started.

now we solve this with by quadratic formula.

so a=1 , b=6, c =8
and we get two values of x which is

but in the question it says we will end up with 3 solutions. Our third solution is actually 
because we took 6x common as the greatest common factor so

so now we have 3 solutions

2) (x-9)(4x+1)=0
since this equation is already in root form we equate each root to 0

so our solutions are x=9 and x=-1/4
3)

now since we need to solve using square roots we apply square roots on both sides

since when we take the square root of a number we get positive and negative of that number example here
x+5=±12
so
x+5=12 and x+5=-12
x=7 and x=-17
4) Difference of two squares means we just need to factorize it in root form so lets begin,

now if we see this expression can be written like this as well

and if we expand this into the difference formula which is

we get

where a is 2x and b is 7
1 3/8 +2 7/83+3/8+7/8
3+1 2/8
3+1 1/4
4 1/4
