The roots of imaginary numbers for solving equations -5x square + 8x-5

-5 * x2 + 8 * X-5 = 0?
We can directly use the binary root formula, x1,2 = (- B plus minus root sign deta) / 2A
If there is a negative number in the root sign, you can directly correct it by adding I
For example, 2 + radical - 4 becomes 2 + 2I
