Answer:

- 12/5

Step-by-step explanation:

= > (x + 4)² + (x - 4)² = 2x(x - 5) + 8

= > (x² + 4² + 2*4*x) + (x² + 4² - 2*4*x) = 2x² - 10x + 8

= > x² + 16 + 8x + x² + 16 - 8x = 2x² - 10x + 8

= > 2x² + 32 = 2x² - 10x + 8

= > 2x² + 32 - 2x² + 10x - 8 = 0

= > 32 - 8 + 10x = 0

= > 24 + 10x = 0

= > 10x = - 24

= > x = - 24/10

= > x = -12/5

Answer:

x=4 or x=-1

Step-by-step explanation:

2(x+4) + 2(x-4) = 2x(x-5)+8

2x + 8 + 2x - 8 = 2x² - 10x + 8

4x - 10x = 2x² + 8

-6x = 2x² + 8

2x² - 6x + 8 = 0

x² - 3x + 4 = 0

(x² + x)  (-4x + 4) = 0

x(x+1) - 4 (x+1)

(x-4) (x+1)

x=4 or x=-1
