Question 997936
Can the quadratic member be factored?
{{{x^2-30x+50=0}}}


2*25, 5*10, but none seem to work:
(x___2)(x___25), no.
(x___5)(x___10), no.



Use formula for general solution to a quadratic equation.
Discriminant,  {{{(-30)^2-4*1*50=900-200=700}}};


{{{x=(30+- sqrt (700))/2}}}


{{{x=(30+- 10sqrt(7))/2}}}


{{{highlight(x=15+- 5sqrt(7))}}}
