Question 545992
Please help me find all the zeros of the functions and write the polynomial as a product of linear factors: 2x^4+5x^3+5x^2+20x-12
--------------------
Try the factors of 12, both + and minus.
If necessary, try them /2, since the MS coeff is 2.
-----------
f(x) = 2x^4+5x^3+5x^2+20x-12
Find f(1), f(2), f(3) plus and minus
-----
Do them manually, or make and Excel sheet.
