We have given with the polynomial y equals to f x equals to x to the power 4 plus 2x cube minus 5 x square minus 4x plus 6.
00:14
Now we have to find only rational root of the function that are so again we can use the formula.
00:26
So, for the possible roots will be plus or minus 1, 2, 3 and 6 divided with 1.
00:34
So again using the here synthetic division method, using synthetic division method.
00:49
So this will be 1, this will be 2, this will be minus 5, this will be minus 4, this will be 6.
00:55
So for this i am taking 1.
01:01
So using 1 .1.
01:03
So this will be 1.
01:04
So this will be 3.
01:06
So this will be 3.
01:07
So this will be minus 2.
01:10
So this will be minus 2...
