Question 354053
ax^2+bx+c=0
x^2+7x-3=0
You want to use the quadratic formula in order to get the exact answers.
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
For our problem a = 1, b = 7, c = -3. Plug them into the formula.
{{{ x = (-7 +- sqrt( 7^2-4*1*(-3) ))/(2*1) = (-7 +- sqrt( 49+12 ))/(2) = (-7 +- sqrt( 61 ))/(2) }}}
