Let ​ x2−12x=61 .​ What values make an equivalent number sentence after completing the square?

Answer 1

I did the math and there were two answers 1. 15.849 2. 3.849

Answer 2

The given equation is $x^2-12x=61$. Add 36 to both the sides of the equation, then

$x^2-12x+36=61+36$.

The equation becomes,

$x^2-12x+6^2=97\\ (x-6)^2=97$
