Question 824969
Find a cubic function with the given zeros.
square root of 5,-square root of 5 and -7


{{{x = sqrt(5)}}}, {{{x = -sqrt(5)}}} or {{{x = -7}}}


{{{x-sqrt(5)=0}}}, {{{x+sqrt(5)=0}}}, or {{{x+7=0}}}

 
{{{(x-sqrt(5))(x+sqrt(5))(x+7)=0}}} 


{{{(x^2-(sqrt(5))^2)(x+7)=0}}} 


{{{(x^2-5)(x+7)=0}}} 


{{{x^2(x+7)-5(x+7)=0}}} 


{{{x^3+7x^2-5x-35=0}}} 


==============================================================


Final Answer: {{{x^3+7x^2-5x-35=0}}}
