WebIf we change our equation into the form: ax²+bx = y-c Then we can factor out an x: x (ax+b) = y-c Since y-c only shifts the parabola up or down, it's unimportant for finding the x-value of the vertex. Because of this, I'll simply replace it with 0: x (ax+b) = 0 Now, we just solve for x: x = 0 and ax+b = 0 x = -b/a WebMar 28, 2024 · ∥X∥by Cauchy-Schwartz 1 Properties of Positive Linear Functionals on C*-Algebras ...
