Answer

$x=3-i,3+i$

Work Step by Step

Plug the values $a$, $b$, and $c$ into the quadratic formula and simplify all the values. $x^2-6x+10=0$ $a=1,b=-6,c=10$ $x=\frac{-b±\sqrt {b^2-4ac}}{2a}$ $x=\frac{-(-6)±\sqrt {(-6)^2-4(1)(10)}}{2(1)}$ $x=\frac{6±\sqrt {36-40}}{2}$ $x=\frac{6±\sqrt {-4}}{2}$ $x=\frac{6±2i}{2}$ $x=3±i$ $x=3-i,3+i$
