Which answer is correct?


Sagot :

The answer to the synthetic division is [tex]x^{2}[/tex]+9[tex]x[/tex]-2+0/x-5

A synthetic division is shorthand method used to divide a polynomial function by a binomial in the form x-c where c is a constant

To divide a polynomial function by a binomial x-c, we set up as though we are doing long division in the form,using our question above;

x-5[tex]\sqrt[/tex][tex]x^{3}[/tex]+4[tex]x^{2}[/tex]-43x-10

To divide using synthetic division, we set aside the coefficients of the dividend and the divisor then multiply with the divisor in this form:

5[tex]\sqrt[/tex]1  4 -43 10

       5  45 10

    1  9   2   0

The quotient would then be based on the above; [tex]x^{2}[/tex]+9[tex]x[/tex]-2+0/x-5

We apply the values under the line as our new coefficients for the quotient but note from answer that the quotient's degrees is one less than the dividend's degrees.
