What number should be added to both sides of the equation to complete the square.

X^2+12x=11

Answer 1

36

Explanation:

The coefficient of the x term in your X^2+12x=11 is 12.

Take half of that, obtaining 6.

Square this result, obtaining 36.

Add this number to both sides, obtaining x^2 + 12x + 36 = 11 + 36
