Question

if the roots of the equestion given below are equel then the value of C is 3xsqure- 4x +c =0​

Answer 1

4/3

Step-by-step explanation:

given roots are equal say a

then, a+a = -(-4)/3 = 4/3

2a = 4/3

a = 2/3

now,

a*a = c/3

(2/3)*(2/3) = c/3

c/3 = 4/9

c = 4/9*3

c= 4/3

Answer 2

Answer:

3x^2-4x+c=0

Step-by-step explanation:

D=b^2-4ac

(if the roots are equal then its discriminant will be 0)

0=(-4)^2-4×3×c

0=16-12c

12c=16

c=16/12

c=4/3
