Solve |5x+30|=10x .

Option A

Step-by-step explanation:

We need to solve out ,

We can write it as ,

On simplyfing further,

On solving the above equation , we will get ,

Now we know that the value of modulus is never negative so when we will put x is equal to 2 on the RHS we will get -20 which is not possible . Therefore , the extraneous root is -2 .

Option A is correct .
