x4 -8x2 - 9 =0
Factorise =
(x2+1)(x2-9)=0
x2+1 =0 so x is square root of -1 which is impossible.
the other equation is (x+3)(x-3) = 0
here x is equal to +3 or -3.
The zero in this question means that the LHS if equal to the RHS which is zero.
You are interested in working out x.

78900000000 scientific notation?
Scientific notation is when you remove all the zeros from the number so you end up with 789. Then you put a decimal between the first and second numbers. After that you put a x10 then count all the zeros and put it to that power.
What the 1 equals 1?
Yes, one equals one. If you get that when solving an algebraic equation, the equation is true for all real numbers.
How do you find the zeros in an equation by looking on a graph?
They are all the points where the graph crosses (or touches) the x-axis.

100 time 660 equals?
It equals 66,000. Whenever multiplying 10, 100, 1000, etc. all you need to do is add the number of zeros in your multiplier (in your case, 100, so 2 zeros) to whatever you're multiplying. So, in 660 x 100 you take the 2 zeros from 100 and add them to the end of 660.
