What number should be added to both sides of the equation to complete the square?<br> x2 + 12x = 11
makkiz [27]

given:

x² + 12x = 11

perfect square:

a² + 2ab + b²

a² = x² ⇒ x * x

2ab = 12x ⇒ 2(6)x

b² = 6² ⇒ 36

x² + 12x + 36 = 11 + 36

(x+6)(x+6) = 47

Both sides must be added with 36.

Hi there!

Answer:

<u><em>A. 12. x=12 and 12=x</em></u>

Step-by-step explanation:

addition property of equality is adding the same number both sides of an equation does not change the equation.

subtraction property of equality is subtraction the same number from both sides of an equation does not change the equation.

multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.

division property of equality is dividing both sides of an equation by the same number non-zero number does not change the equation.

x-6=14-8

subtract by 6 both sides of an equation.

x-6=6

add by 6 both sides of an equation.

x-6+6=6+6

simplify.

6+6=12

x=12

12-6=6

Hope this helps!
