I assume you mean,

X2 + 12X - 5 = 0

X2 + 12X = 5

Now, halve the linear term (12), square it and add it to both sides

X2 + 12X + 36 = 5 + 36

factor on the left, gather terms on the right

(X + 6)2 = 41

(X + 6)2 - 41 = 0

==============vertex form.... (- 6, - 41)

========================--------------vertex

And that number added is 36

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.

What number must be added to both sides of the equation to complete the square x2 12x-6?

To complete the square for the expression (x^2 + 12x - 6), we need to focus on the (x^2 + 12x) part. We take half of the coefficient of (x) (which is 12), square it, and add it to both sides. Half of 12 is 6, and squaring it gives us 36. Therefore, we must add 36 to both sides of the equation.

What number must you add to complete the square of x2 plus 12x equals 40?

The constant term - the part without a variable - must be equal to the square of one half the linear term - the number in front of the "x". That is, it must be (12/2)2 = 36.


How do you complete the square x squared plus 12x equals 5?

x^2 + 12x = 5 x^2 + 12x + __ = 5 + __ x^2 + 12x + 36 = 5 + 36 (The 36 I got from taking half of 12 and then squaring that number (which is 6).) (x + 6)^2 = 41 x + 6 = (the square root of 41) x = (the square root of 41) - 6. Hope that helped :)

What number must you add to complete the square x2 plus 12x equals 16?

Add? I will show you the process. X^2 + 12X = 16 halve the linear term (12), square it and ADD it to both sides X^2 + 12X + 36 = 16 + 36 factor the right side; gather terms right (X + 6)^2 = 52 (X + 6)^2 - 52 = 0 (-6,-52) vertex of function As you see 36 was added to both sides
