Answer:

x=\frac{5\±i√203}{6}(the lanky a is a square root)

Step-by-step explanation:

I suppose the equation is 3x^2-5x+19=0?

A good old quadratic equation! Back to the good old days when we are memorizing the formula...

x=\frac{-b\±√(b^2-4ac)}{2a}

(Yes that little lanky a is a square root)

x=\frac{-(-5)\±√((-5)^2-4(3)(19))}{2(3)} \\x=\frac{5\±√(25-228)}{6}\\x=\frac{5\±√-203}{6} \\x=\frac{5\±i√203}{6}

Since the discriminant is negative, there are no real solutions, but instead, we have complex solutions shown above.
