Solve the quadratic equation 3x²+x-5=0

1 answer:

8 0

This does not look easy to factor, so I'd suggest using the quadratic formula:
-1 plus or minus sqrt( 1-4(3)(-5) )
x = -----------------------------------------------
2*3

-1 plus or minus sqrt(61)
= ------------------------------------
6

Thus, there are 2 real, unequal, irrational roots / solutions.
