Question 146017
x^2+5x + 6 = 0
:
The quadratic formula:
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
:
In your problem a=1; b=5; c=6
{{{x = (-5 +- sqrt( 5^2 - 4*1*6))/(2*1) }}}
:
{{{x = (-5 +- sqrt(25 - 24))/(2) }}}
:
{{{x = (-5 +- sqrt(1))/2}}}
:
Two solutions:
{{{x = (-5 + 1)/2}}}
x = {{{(-4)/2}}}
x = -2
and
{{{x = (-5 - 1)/2}}}
x = {{{(-6)/2}}}
x = -3
