Mathematics: 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)

From Pythagorean we know x^2 + y^2 = z^2. (x and y are smaller than z).Let’s try!21^2 + 220^2 = 441 + 48400 = 48841.221^2 = 48841. The same!So the answer is yes, you can make a right angled triangle....

Mathematics

u^2-u-6=0

where

u=(x-4)

Step-by-step explanation:

we have

(x-4)^2-(x-4)-6=0

Let

u=(x-4)

substitute in the expression above

(u)^2-(u)-6=0

Solve for u

Complete the square

(u^2-u+0.25)=6+0.25

(u^2-u+0.25)=6.25

Rewrite as perfect squares

(u-0.5)^2=6.25

square root booth sides

$u-0.5=\pm2.5$

$u=0.5\pm2.5$

u_1=0.5+2.5=3

u_2=0.5-2.5=-2

Solve for x

Remember that

u=(x-4)

For u=3

3=(x-4) ----> x=7

For u=-2

-2=(x-4) ----> x=2

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)
