Question 75981
{{{x^2 = 7x + 6}}}
{{{x^2 - 7x - 6=0}}} [set the equation equal to zero by subtraction 7x and 6 from both sides]
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} [plug-in the values]
{{{x = (-(-7) +- sqrt( (-7)^2-4*1*-6 ))/(2*1) }}} [simplify]
{{{x = ((7) +- sqrt( 49+24 ))/(2) }}}
{{{x = ((7) +- sqrt( 73 ))/(2)) }}}
.
x=7.772 or x=-0.772
