Hello everyone,

Could someone please tell me if this is the correct way to complete the square? If not, could you please show me where I went wrong?

11a^2+7a=6

11a^2+7a-6=0

11(a^2+7/11a-6/11)=0

11(a+7/11/2)^2-7/11-6/11=0

11(a+7/11/2)^2=13/11

(a+49/121)^2=13/121

a+49/121=square root(13/121)

a=-.077

Thank you very much
