Plz answer the question. ​

Answer 1

Step-by-step explanation:

given equation,

3x^2-12x+m=0..

here, a=3 b= -12 c= m

if the roots are equal .

then the roots will be -b/2a , -b/2a

so , the roots of the equation are -(-12)/(2×3) = 2

the roots of the given equation are 2,2

as we know that product of the roots =c/a

then, c/a=2×2

m/3=4

m=3*4

m=12
