Answer:

x=√139-3, x=-√139-3

Step-by-step explanation:

to complete the square, you first move the constant to the other side of the equation-its already done for you!

now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.

What you do to one side has to be done with the other.

x^2+6x+9=130+9

now you can factor the square:

(x+3)^2=139

squareroot both sides:

x+3=√139

x+3=-√139

now subtract both sides by 3

x=√139-3

x=-√139-3
