well, for problems like these, this is what I do (I'll try my best at explaining): Take the last number (the -5) and take all the factors that make this up (±1, ±5). Then do the same for the leading coefficient (3), which gives you (±1, ±3). Put the factors of the -5 over the factors of 3 to...

Ok, I hope there’s a math wiz out there who can help me. I have to factor: f (x)=3x^4-8x^3-5x^2+16x-5 Just from looking at it, you know that possible values for x are: ±1, ±5/3, ±1/3, ±5 However, if you plug in these real numbers, none of them work, therefore meaning that x is an...
