I expect the second term is NOT 6x15in which case, there is an arithmetic symbol missing between 6x and 15.
x2+ 6x + 9 is the completed square so you will need to work out what needs to be added: depending on -15 or +15.

The idea is to take half the linear part (12, in this case), then square it. The constant part must be equal to this result.
square root -5 minus 14 or - square root -5 minus 14
81. To complete the square, halve the coefficient of the x term (18/2 = 9) and add the square of this (92 = 81) to both sides: x2 + 18x = -13 ⇒ x2 + 18x + 81 = -13 + 81 ⇒ (x + 9)2 = 68
You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.

You must add 1
You must add (17n + 144).

it is 121
49/4 or 12.25

Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.
94
You need to add -22.
