Question

What values of b satisfy 3(2b+3)^2 = 36

Answer 1

$\frac{-3 +/- 2 \sqrt{3} }{2}$

Start by dividing both sides by 3. Then take the square root of both sides. Then subtract 3 from both sides and divide by 2.  

Answer 2

$( \sqrt{12 } - 3) \div 2$
dividing both side by 3
then, taking square root on both side
then you will get value of b and above form in the equation
