Question 927103

first find the roots:

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

if {{{(x-5)=0}}}=> {{{x=5}}}

if {{{(x+2)=0}}}=> {{{x=-2}}}

so, roots are  {{{x=5}}} and {{{x=-2}}}

the sum of the roots is {{{s=5+(-2)=5-2=3}}}

the product of the roots is {{{p=5*(-2)=-10}}}

by what amount does the sum of the roots exceed the product of the roots

if {{{a=amount}}} then

{{{s=p+a}}}

{{{3=-10+a}}}

{{{3+10=a}}}

{{{13=a}}}..the amount by what the sum of the roots exceed the product of the roots
