2 answers:
Answer:
a=1/2, b=-3, c=-2
Step-by-step explanation:
Given quadratic equation is
y=
Quadratic equation is in the form of y =ax^2 +bx+c
WE compare the equation and find the value of a,b,c
The value of 'a' is the value before x^2 . a=1/2
the value of 'b' is the value before x . b= -3
the value of 'c' is the constant . c=-2
so the value of a,b,c is a=1/2, b=-3, c=-2
