Please help, and may you explain it? :( also there IS a negative on the 6 if you were wondering... c:

b= -6.

Step-by-step explanation:

To do this, we will need to distribute the '5' to simplify this equation:

-6+5·(-1)+5·(-b)=19

-6-5-5b=19

Now, continue simplifying:

-11-5b=19

-5b=30

-5b=30

Divide both sides by -5, giving us:

b=-6. Here is your answer! Have a great day!

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
