Answer:
153
Step-by-step explanation:
Answer:
Distributive
Step-by-step explanation:
C= -3 and d=15
I took the 'c' term out of the left side
c multiplied by 4x makes -12x so c must be -3
that means that -3 multiplied by -5 equals d (which is 15)
Answer:
(2, -10)
Step-by-step explanation:
so first i find the axis of symmetry using the equation x= -b/2a
in this problem
a=3
b= -12
c= 2
- (-12)/ 2(3) = 2
2 will be the x point for your vertex
you then plug in your x point into the original equation and solve for y
y = 3(2)^2 - 12(2) +2
y = -10
Vertex is then (2, -10)
