What is the solution?

Ilia_Sergeevich [38]

Answer:

A. { $3+7i,3-7i$ }

Step-by-step explanation:

The given equation is $x^2-6x+58=0$

Use the quadratic formula with a=1,b=-6 and c=58

Recall the quadratic formula;

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

We substitute the given values to get;

$x=\frac{--6\pm \sqrt{(-6)^2-4(1)(58)} }{2(1)}$

$x=\frac{6\pm \sqrt{36-232} }{2}$

$x=\frac{6\pm \sqrt{-196} }{2}$

Recall that;

$\sqrt{-1}=i$

$x=\frac{6\pm 14i}{2}$

$x=3\pm 7i$

$x=3+7i$ or $x=3-7i$
