GCF is first so
3(6x^2+5x-4)
Do the X method
-24 (top of the X)
5 (bottom of X)
-3 (right side of X)
5 (left side of X)
6x^2-3x+5x-4
Take the first 2 numbers and solve
6x^2-3x
3x(2x-1)
And then take the next 2 numbers
5x+4 you cant do anything here so it stays the same
Just add them all together and you get ur answer
