FACTOR THE TRINOMAL

10x^3-26x^2-12x

Please help me I know that you would do 10*(-12)
because you would do mn=10*(-12) then m+n=26
then you will do the chart
1,-120 -1,120 10, -12 -10, 12 then what

are you sure because what I have learned is that you find the equations for such as mn=ac and m+n=b

Not entirely certain what formula or chart you're learning in class. But here's how I would approach it: You can factor out 2x right away since all the coefficients are even and every term has an x, giving you 2x(5x^2-13x-6), then work the inside:

Should be something like. (5x+?)(x-?) or (5x-?)(x+?). Only a couple different ways that will go. (5x+2)(x-3) looks about right. 5*3-2 will give you the 13.

Giving you the final result 2x(5x+2)(x-3).

that is what I came up with also so I would put the 2x in from right
