Answer:
The value of m is 5 or 0
Step-by-step explanation:
Value of m is 0 Or 5
Step-by-step explanation:
We have,.
m(5x - 6) + 9 = 0
=> 5m * x ^ 2 - 6mx + 9 = 0
Compare this equation with a * x ^ 2 + bx + c = 0 we get
a=5m, b = - 6m , c = 9 ,
Discreminant (D) = 0
/* Roots are equal */
=> b²-4ac=0
=> (-6m)²-4x5mx9 =0
=> 36m²-36x5m =0
=> 36m(m-5)=0
=> 36m = 0 Or m-5 = 0
=> m=0 Or m = 5
Therefore,
Value of m is 0 Or 5
