2 answers:
Answer:
.
Step-by-step explanation:
Given : -6x² = 3 -4x.
To find : What is the discriminant of the quadratic equation .
Solution : We have given that -6x² = 3 -4x.
Rewrite the equation : -6x²+ 4x -3 = 0.
Standard form of quadratic form : ax²+ bx + c = 0.
Discriminant = .
Then, a = -6 , b =4 , c =-3

Answer:
The equation of parabola is given by :
Step-by-step explanation:
Given that vertex and focus of parabola are
Vertex: (4,-3)
Focus:(,-3)
The general equation of parabola is given by.
, When x-componet of focus and Vertex is same
, When y-componet of focus and Vertex is same
where Vertex: (h,k)
and p is distance between vertex and focus
The distance between two points is given by :
L=
For value of p:
p=
p=
p=
p= and p=
Since, Focus is left side of the vertex,
p= is required value
Replacing value in general equation of parabola,
Vertex: (h,k)=(4,-3)
p=
