Question

Find the value of m so that the quadratic equation mx(5x − 6) = 0 has two equal roots.​

Answer 1

Answer:

M=0 AND M=5/9

Step-by-step explanation:

As we all know that ,

for equal roots , we put D=b^2-4ac=0.

At first resolve the quadratic equation,

5mx^2-6mx=0;

here,for the above equation;

b=-6m,a=5m,c=1;

D=b^2-4ac=0;

36m^2-4(5m)(1)=0;

36m^2-20m=0;

4m(9m-5)=0;

4m=0;9m-5=0;

m=0,5/9.

hope you understand my explanation,thanks.

Answer 2

Answer:

$m = 5$, so that the quadratic equation $mx(5x - 6) = 0$has two equal roots.
