Question

Complete the square to transform the quadratic equation into the form (x p)2 = 9. x² - 128 - 5=7 A) (X - 36)2 = 9 B) (x - 6)2 = 48 (x-36)2 = 9 . D) (x-6)2=-48

Answer 1

x^2 - 12 x - 5 = 7

then

(x^2 - 2•6x + 6^2 ) - 5 = 7 + 6^2

( x-6 )^2 = 7+36 + 5 = 48

THEN answer is

Option B) (x-6)^2 = 48
