Easy...
to even begin to factor..you must factor out a 3, to simplify your answer.
3(12\(x^{2}\)-7x-10)
Now, you can factor.
\(3(12 x^{2} -7x-10)\)
So..to find the answer...
12-10=-120x
andÂ
you would use -7x
What multiplies to -120..but adds to -7?
-158=-120
and
-15+8=-7
To find the answer, plug in what you know..
3(3x+2)(4x-5)
Thus, your answer.
