-3x^2 + 36x - 120
---
the above quadratic equation is in standard form: y = ax^2 + bx + c
with a=-3, b=36, and c=-120
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
-3 36 -120
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic vertex is a maximum at: ( x= 6, y= -12 )
---
vertex form is:
y = a(x – h)^2 + k
where (h, k) is the vertex and,
where "a" in the vertex form is the same "a" in the standard form:
y = ax^2 + bx + c
---
answer:
y = -3(x – 6)^2 - 12
