Find x3 6x2 8x 7x 7 SolutionStep 1 take all the coeffici

Solution

Step 1) take all the coefficients of the polynomials and set a root of equation of denominator as x=-7

The coefficients are

-7 ! -1 -6 8 7

! 7 -7 -7

.......................................

-1 1 1 0

In step 1 we take -1 as it is in down

Step 2 we multiply -1by -7 and added this product to 6 and sum is written down likewise we get last step

Ans is -x^2 +x +1
