Which quadratic equation is equivalent to (x - 4)2 – ( - 4) - 6 = 0?
(u - 4)2 – (u - 4) - 6 = 0 where u = (x - 4)
o v2-(u - 4) - 6 = 0 where u = (x - 4)
o 02 - 16 - 4-6 = 0 where u = (x - 4)
o 02-4-6 = 0 where u = (x - 4)

where

Step-by-step explanation:

we have

Let

substitute in the expression above

Solve for u

Complete the square

Rewrite as perfect squares

square root booth sides

Solve for x

Remember that

For u=3

---->

For u=-2

---->

answer: no
