Question

Let ​ x^2−12x=61 .​ What values make an equivalent number sentence after completing the square? Enter your answers in the boxes. HELP PLEASE

Answer 1

A=1 , b=-12 , c=61. B^2-(4 •a•c) = d
-12^2-(4•1•61)= d
X= (-b-sqr (d) ) / 2a or x=(-b+sqr (d) )/2a

Answer 2

Complete the square:

x^2 - 12x + (-6)^2 - (-6)^2 = 61, or
(x-6)^2 -36 = 61, or

x-6 = plus or minus sqrt(97), or

x = 6 plus or minus sqrt(97)
