-x^2+5x-6=2\\-x^2+5x-6-2=0\\-x^2+5x-8=0\\

↝ Form into
ax^2+bx+c = 0 where a > 0 (Optional)


x^2-5x+8=0 ↝ Multiply -1 for both sides.

↝ Then proceed with the Quadratic Formula.

x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula


x=(-(-5)+-√((-5)^2-4(1)(8)))/(2(1))\\x=(5+-√(25-32))/(2)\\

↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.

Solution with Real Numbers System There are no real solutions.

Solution with Complex Number System


x=(5+-√(25-32))/(2)\\x=(5+-√(-7))/(2)\\x=(5+-√(7)i )/(2)

Therefore, the answer for Complex Number System is (5±√7i)/2
