Question 43982
{{{7/8x^2-3/4x +5/16=0}}} 
Use the quadratic solver {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} to give:
{{{x = ((3/4 +- sqrt( (9/16)-4*(7/8)*(5/16) )))/(14/8) }}}
{{{x = (3/4 +- sqrt( -17/32))/(14/8) }}}
{{{x = ((3/7) +- sqrt( (-17/32)))/(14/8) }}}

P.S. I am trying to start up my own homework help website. I would be extremely grateful if you would e-mail me some feedback on the help you received to adam.chapman@student.manchester.ac.uk
