How do you graph the quadratic formula x^2-10x=11? Here's what I got so far:
In standard form, it's x^2-10x-11=0.
Axis of Symmetry: 10^2/2(1)=50
Quadratic Formula: 56 and 44
<<How do you graph the quadratic formula x^2-10x=11?>>
your question makes little sense, we do not
"graph" the quadratic formula.
Are you solving the equation?
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
