Question

use the quadratic formula to find any x-intercepts on the graph of the equation.
y=x^2-2x-2

Answer 1

\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] with
\[a=1,b=-2,c=-2\]

Answer 2

in fact for this one it is easier to "complete the square"
\[x^2-2x-2=0\]
\[x^2-2x=2\]
\[(x-1)^2=2+1=3\]
\[x-1=\pm\sqrt3\]
\[x=1\pm\sqrt3\]
