You can put this solution on YOUR website! How would you us e the quadratic equation to answer:
4z^2+z-6=0
-----------------
ForM x = [-b +- sqrt(b^2 - 4ac)]/(2a)
----------------------
Your Problem:
a = 4 ; b = 1 ; c = -6
----------------------------
z = [-1 +- sqrt(1 -4*4*-6)]/(2*4)
---
z = [-1 +- sqrt(1+ 96)]/8
z = [-1 +- sqrt(97)]/8
z = [-1 + sqrt(97)]/8 or z = [-1 - sqrt(97)]/8
===================================================
Cheers,
Stan H.
