lol
Rational numbers are numbers that don’t repeat or terminate... i think...
So i say false... but i may be wrong...

...? 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.
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?
well, its not about solving it. its about getting it to this form (n will equal a number or variable or number variable combo or whatever...and, plus and minuses are interchangeable. each n may or may not be different) (n+n)(n+n). its basically the reverse of simplifying it.

lol. its ok. its a bit beyond me, and math is what i do best. that is why i hate factoring, btw. its extreamely complicated....maybe kyle would know...i’m in algebra 1 also, but all classes, and probably schools also, go at their own pace and order.
