Question

Solve the quadratic equation
x^2-(2+I)x-(1-7i)=0

Answer 1

Answer:

$\frac{2+i-\sqrt{7-24i} }{2} and \frac{2+i-\sqrt{7-24i} }{2}$=

Step-by-step explanation:

Delta =

$b^2-4ac\\(2+i)^2-4(-1+7i)\\4+4i+i^2+4-28i (i^2=-1)\\8-1-24i\\7-24i$

$x1=\frac{-b+\sqrt{delta} }{2a} and x2=\frac{-b-\sqrt{delta} }{2a}\\x1=\frac{2+i+\sqrt{7-24i} }{2} and x2=\frac{2+i-\sqrt{7-24i} }{2}$
