Question

Solve (2b + 1)^2 = 25

Answer 1

Take square root of both sides
2b + 1 = 5 or 2b + 1 = -5
Now, solve the 2 equations, can you?

Answer 2

either you can expand LHS and form a quadratic equation and solve,,or you can see that
25= 5^2 or (-5)^2 ..then you can take root of both sides and solve for b,,you should get 2 values..

Answer 3

i need the values

Answer 4

Have you tried?

Answer 5

yea

Answer 6

-3 and 2 ..you can check by hit and trial also..this makes it an oral question.

Answer 7

so just -3 and 2 or x=-3 x=2 im askin cause idk

Answer 8

ydk !!?? hmmn,,anyways its b=-3 and b=2..

Answer 9

thanks thats all I wanted

Answer 10

@shubhamsrg unfortunately, hit-and-trial though handy, doesn't always work :)

Simplify the equation, bring every term to the same side, and then factorize the quadratic you get.

Answer 11

well yes it dosent work every time,,but see the given equation,,saves time with hit and trial..umm..
