Urm... what is x?


I’ve a better (stupider) question:
What’s " ^ " that thing mean?

it means to that power. so, its two times x to the second power.


I thought that.
huh
Call me stupid cos I don’t know it.

lol, i just recently learned it.

I look at it this way:
They want me to find X, I shall circle X, put an arrow beside the circle, and write “here it is” on the opposing end of the arrow.
If they wish me to expand an equation, I shall do the following
2x+3y=6
2 x + 3 y = 6
Etc etc.

Okay there are four answers

a: .5
b. .75
c. .3333333……

...? was that to me? i’m saying factoring.

like this....

m^2 - 14m + 40

m^2 - 4m - 10m + 40

m(m - 4) - 10(m - 4)

(m - 10)(m - 4)

and that is the final answer. its sort of complicated how you get the numbers...if you don’t know what i just did, it won’t be worth explaining.

Rational numbers are numbers that don’t repeat or terminate... i think...

So i say false... but i may be wrong...

Isn’t it true? (rational numbers I believe are like 1, 2, 3, 4 all those types)

lol, see edit. i looked it up. “a number that can be expressed exactly by a ratio of two integers." that is pretty much the definition of a fraction.

and that is the final answer. its sort of complicated how you get the numbers...if you don’t know what i just did, it won’t be worth explaining.


So, lets say m is 3, for example.

3^2 - 14X3 + 40

9 - 42 + 40 = 7

Is that it?

Or do you have to break it down and crack it?
