If the equation is let's say 3x+ 7 +4x to combine like terms, you would take 3x and 4x since they both have x. You wouldn't take the 7 since it doesn't have and x like the other numbers. 3x +4x = 7x so your new equation would be 7x + 7.

Answer:
second option
Step-by-step explanation:
Given
x² - 6x - 33 = 0 ( add 33 to both sides )
x² - 6x = 33
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 33 + 9
(x - 3)² = 42 → second option
