X²+4x+20=0 a=1 b=20 c=4
a=1 b=4 c=-20
a=1 b =4 c = 20
a=1 b=-4 c=0

2x²+6x+5=0

-2x²+x+5 identify the coefficients ​

Step-by-step explanation:

The general form of the quadratic equation is :

The given equation is x²+4x+20=0

On comparing the given equation and the general equation, we find that

a = 1, b = 4 and c = 20

Hence, the correct option is a=1 b =4 c = 20.

If the equation is 2x²+6x+5=0, then

a = 2, b = 6 and c = 5

If the equation is -2x²+x+5

a = -2, b = 1 and c = 5
