Question 1181479


Since all coefficients are integers, we can apply the rational zeros theorem.

The trailing coefficient (the coefficient of the constant term) is {{{4}}}.

Find its factors (with the plus sign and the minus sign): ±{{{1}}}, ±{{{2}}}, ±{{{4}}}.

These are the possible values for {{{p}}}.

The leading coefficient (the coefficient of the term with the highest degree) is {{{5}}}.

Find its factors (with the plus sign and the minus sign): ±{{{1}}}, ±{{{5}}}.

These are the possible values for {{{q}}}.

Find {{{all}}} possible values of  {{{p/q}}}:

 ±{{{1/1}}}, ±{{{1/5}}}, ±{{{2/1}}}, ±{{{2/5}}}, ±{{{4/1}}}, ±{{{4/5}}}

simplified:

±{{{1}}}, ±{{{1/5}}}, ±{{{2}}}, ±{{{2/5}}}, ±{{{4}}}, ±{{{4/5}}}


your answer option is:


±{{{1}}}, ±{{{2}}}, ±{{{4}}}
