what values of b satisfy 3(2b + 3)^2 = 36?\no b = (-3 + 2√3)/2 and (-3 - 2√3)/2\no b = (-3 + 2√3)/3 and (-3 - 2√3)/3\no b = 3/2 and -9/2\no b = 9/2 and -3/2
Answer
Explanation:
Step1: Isolate the squared - term
Divide both sides of the equation $3(2b + 3)^2=36$ by 3. $\frac{3(2b + 3)^2}{3}=\frac{36}{3}$, which simplifies to $(2b + 3)^2 = 12$.
Step2: Take the square - root of both sides
$2b+3=\pm\sqrt{12}=\pm2\sqrt{3}$.
Step3: Solve for b
First, consider the case when $2b + 3=2\sqrt{3}$. Then $2b=2\sqrt{3}-3$, and $b=\frac{-3 + 2\sqrt{3}}{2}$. Second, consider the case when $2b + 3=-2\sqrt{3}$. Then $2b=-2\sqrt{3}-3$, and $b=\frac{-3-2\sqrt{3}}{2}$.
Answer:
$b=\frac{-3 + 2\sqrt{3}}{2}$ and $b=\frac{-3-2\sqrt{3}}{2}$
