Question 246123
divide both sides by 12
12b^2+26b+12=0

you can solve by factoring, completng the square or by quadratic formula

You get -3/2 (-1.5) and -2/3 (-.667)
I like completing the square.
12b^2+26b=-12
divide by 12
b^2+(26/12)(b)=-1

b^2+(13/6)(b)=-1
add 1/2*(13/6)^2 =169/144 to both sides
b^2+(13/6)(b)+169/144=25/144
factor
|b+13/12|=-5/12
b=-5/12-13/12=-18/12=-3/2
b=+5/12-13/12=-8/12=-2/3
