Question 1209147
{{{c^2-14c+49=20c+81}}}

{{{c^2-34c-32=0}}}

discriminant, {{{(-34)^2-4*1*(-32)=1156+128=1284}}}
{{{6*214=2*6*107=2*2*3*107}}}, solving for c by factorization not useful
because discriminant not a perfect square.


{{{c=(34+- sqrt(2*2*3*107))/2}}}

{{{highlight(c=17+- sqrt(321))}}}
