I dont understand how to do the difference of cubes thing. And please dont direct me to another website such as purplemath, Ive tried reading it, yet dont understand. Please help!-(a-b) (a^2 + ab + b^
To understand why (x^3)^2 is x^6, let x = 10.
x^3 = 1000.
(x^3)^2 = 1000^2 = 1,000,000 = 10^6 = x^6.
See, the answer is not 10^5.-No
(x^3)^2 equals to x^6
answer
since (x^3)^2 = x ^ 3*2 = x^6-X^6

A thermometer is taken from a room where the temperature is 25°C to the outdoors, where the temperature is -11° C. After one minute the thermometer reads 7°C.

lim x--> 1+ (1 from the right side)
1/(1-x)
1/positive infinity = positive infinity?-1 - x approaches 0 but from the negative side if the x -> 1 +.
(1 - 1.1), (1 - 1.01), (1 - 1.001)... these are al
x+4x=0, x(0)=1, x(0)=-2
please show me how to find the amplitude, phaseangle, and period!
i got as far as utilizing the characteristic equation...
x^2+4 =0
x = +/- 2i
x(t) = Acos(2t)+Bisin(2t)

Show by example that the product of elements with finite order in a group need not have finite order.What if the group is abelian?
I think its something like g^k = g^s
Then (g^k)(g^-k) = (g^s)(g^-k)

I need to factor these polynomials but I dont quite understand them.
a^2+2ab+b^2-c^2
4-a^2-2ab-b^2
x^4-(4x-5)^2
It would be great if someone could show me the steps.-1. (a+b-c)(a+b+c)
2. -(a+b-2)
Im working on a practice SAT and cant figure out this problem...
On a square gameboard that is divided into n rows of n squares each, k of these squares lie on the boundary of the gameboard.Which of
How would you start this problem?
I dont know if you can switch into polar coordinates given a sinx function and e^y function-Its much simpler than that!
lim((x,y)→(0,0)) (sin x)(e^y - 1) / (xy)
= lim
Cant the answer be positive three?-So the way I did it, since you get an indeterminate form of +∞/-∞ when you solve directly is that I divided the numerator and denominator by the highest exponent pow
Can you help me understand how to work a problem like this?
