Question

Find the value of m, if the roots of the equation 3x² + m=5x are equal

Answer 1

Answer:

Step-by-step explanation:

given Eqn is 3x²+m=5x

it can be rewritten as 3x²+m-5x=0

3x²-5x+m=0

if roots are equal then

the discriminant of quadratic equation will zero

therefore D=0

therefore D=b²-4ac. =0

(-5)²-4(3)(m)=0

25 -12m. =0

25=12m

m=25/12
