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
