36x^2-21x-30 factor
Answers
Answer 1
Answer:
Easy...
to even begin to factor..you must factor out a 3, to simplify your answer.
3(12
-7x-10)
Now, you can factor.
)
So..to find the answer...
12*-10=-120x
and
you would use -7x
What multiplies to -120..but adds to -7?
-15*8=-120
and
-15+8=-7
To find the answer, plug in what you know..
3(3x+2)(4x-5)
Thus, your answer.

the way i do it, is i want 12 to be recurring, so i do 12/100, then i take away one from the denominator, so i get 12/99 = 0.121212.....
similarly, if i wanted 0.123123123,
i could do 123/1000 then take away one from the denominator to get 123/999 and that should give us 0.123123123123
