Question

for what value of 'a' quadratic equation 3x^2-4c+a =0 has equal roots​

Answer 1

Answer:

comparing 3x²-4c+a = 0 with ax²+bx+c = 0

a = 3 , b = -4 ,c = a

the roots are equal

b²-4ac = 0

(-4)²-4×3×a = 0

16 - 12a = 0

-12a = 0 - 16

-12a = -16

-a = -16/12

-a = -4/3

a = 4/3

Answer 2

Answer:

Answer:

comparing 3x²-4c+a = 0 with ax²+bx+c = 0

a = 3 , b = -4 ,c = a

the roots are equal

b²-4ac = 0

(-4)²-4×3×a = 0

16 - 12a = 0

-12a = 0 - 16

-12a = -16

-a = -16/12

-a = -4/3

a = 4/3
