Find all rational zeros of the function:
f(x)=25x^4+25x^3-154x^2-4x+24
ok i found the two zeros 2 and -3, now i dont know how to factor it please help i dont understand how to get the answear
(x-2)(x+3) (.....
Multiply the two that you found to get x^2+x-6 and then divide by that.
I can't teach you polynomial division on here but you could choose a video from here..

Yes that's correct. Now factorise 25x^2-4. It's a difference of two squares.
