Question 50942
{{{x^2+ 4x-12=0}}}

the formula under is the quadratic formula:
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}


{{{x = (-4 +- sqrt( 4^2-4*-12 ))/(2) }}}
{{{x = (-4 +- sqrt( 16+48 ))/(2) }}}
{{{x = (-4 +- sqrt( 64 ))/(2) }}}
{{{x = (-4 +- 8)/(2) }}}


two avaible answers;
first:
{{{x = (-4 - 8)/(2) }}}
{{{x = -6) }}}
second:
{{{x = (-4 + 8)/(2) }}}
{{{x = 2 }}}
