Question 971885
{{{ 3x^2 + 3 = 7x }}}
You need to get this into the form:
{{{ ax^2 + b*x + c = 0 }}}
------------------------
Subtract {{{ 7x }}} from both sides
{{{ 3x^2 - 7x + 3 = 0 }}}
You can use the quadratic formula
{{{ x = ( -b +- sqrt( b^2 - 4*a*c )) / (2*a) }}}
{{{ a = 3 }}}
{{{ b = -7 }}}
{{{ c = 3 }}}
{{{ x = ( -(-7) +- sqrt( (-7)^2 - 4*3*3 )) / (2*3) }}}
{{{ x = (  7 +- sqrt( 49 - 36 )) / 6 }}}
{{{ x = ( 7 + sqrt( 13 ) ) / 6 }}}
and
{{{ x = ( 7 - sqrt( 13 ) ) / 6 }}}
