In standard form, it's x^2-10x-11=0.

Discriminant: -10^2-4(1)(-11)=144

Axis of Symmetry: 10^2/2(1)=50

Quadratic Formula: 56 and 44

Thank You!

your question makes little sense, we do not

"graph" the quadratic formula.

Are you solving the equation?

then ...

x^2 - 10x - 11 = 0

which factors nicely to

(x-11)(x+1) = 0

so x = 11 or x = -1

there is no "axis of symmetry" here, to have one you would need the corresponding quadratic function

f(x) = x^2-10x-11

You could graph this, its vertex would be (-5,64)

and the axis of symmetry for that parabola would be x = -5
