C an anyone solve this 3(2b + 3)2 = 36<br> and if so what is it

Natali [406]

$3(2b + 3)^2 = 36$

Divide by 3 on both sides:
$(2b + 3)^2 = 12$

Square root both sides:
$2b + 3= \pm \sqrt{12}$

Take away 3 from both sides:
$2b= \pm \sqrt{12} - 3$

Divide by 2 on both sides:
$b= \dfrac{ \sqrt{12} -3 }{2} \ or \ b= \dfrac{ -\sqrt{12} -3 }{2}$

Answer:
$b= 0.23 \ or \ -3.23$
