how would I solve x^2 - 4x + 10 = 0
u can use quadratic formula for this
oh wow! I didn't even think of that possibility. Thank you :)
\[x= \frac{ -b \pm \sqrt {b^2-4ac} }{ 2a }\] where a=1, b=-4 and c=10
sometimes, a quadratic equation has no solution if D<0 (with D=b^2-4ac) do u have checked it
that doesn't mean no solution that means, equation will have complex root which can be obtained further
