Question

Plzz tell the reason of this answer that why, there is (2s-1) why not (2s+1) where i have done a circle .plzz tell the right answer and i will mark as brainliest and i will follow you. IF YOU WILL GIVE RUBBISH ANSWERS I WILL REPORT YOUR ANSWER. ​

Answer 1

Step-by-step explanation:

4s²-4s+1=0

4s²-2s-2s+1=0

2s(2s-1)-1(2s-1)=0

Here you got (2s-1) because you have taken -1 as the common factor. You have correctly solved the quadratic equation because the terms in the brackets should be equal and you have made them equal by taking the common factor as -1.

If you want to solve further you can do it like this.

(2s-1)(2s-1)=0

Therefore s = 1/2
