Question

Rewrite quadratic equation
-×^2+2x-10

Answer 1

it has no solution because it is not factorable 

Answer 2

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

a=-1, b=2, c=10

x=$\frac{-2+/- \sqrt{4-4(-1)(10)} }{2(-1)}$

x=$\frac{-2+/- \sqrt{44}}{-2}$

x=$\frac{-2+/-2 \sqrt{11}}{-2}$

x=${1+/-(-1)\sqrt{11}$
